Math 6 Module #1 Week 1
Area and Perimeter of Rectangles
SOL 6.7c) solve problems, including practical problems, involving area and perimeter of triangles and rectangles.
After completing this presentation you should be able to calculate the area (A) and Perimeter (p) of various rectangles and understand when to use each measure when applied to practical (word) problems.
First let’s review some facts about rectangles: - Rectangles are 4-sided polygons with 4 right
or 90 degree angles. - Also it is important to remember that opposite
sides of a rectangle are congruent or equal in length.
- Squares are special rectangles where all 4 sides are congruent or equal in length.
Perimeter (p) is the distance around the outside of a shape or figure. We would need to know the perimeter if we were building a frame for a picture or fence around a garden. The thick black line represents the perimeter of the rectangle shown.
Perimeter (p) is the sum of all of the sides of a rectangle. We know that if the left side is 7 inches long then the right or opposite side must also be 7 inches long. Likewise if the bottom side is 10 inches long then the top side must also be 10 inches long.Therefore the perimeter (P) = 7 + 7 + 10 + 10 or P = 34 in.
10 in.
7in. 7 in.
10 in.
Perimeter is always measured in units of length, such as inches, feet, yards, centimeters, meters etc.
Since all 4 sides of a square are equal or congruent, we can add side + side + side + side. But it might be easier to multiply the side length (s) by 4.So the formula is p = 4S*You can use either method (multiplication or addition) to find the perimeter*
The VDOE formula sheet lists this formula for perimeter (p) of a square.
So for the above square, the perimeter p = 4(5) or p = 20 cm.If you prefer adding then, p = 5 + 5 + 5 + 5 or p = 20 cm.
Be sure to always include units in your answer!
5cm.
5cm.
The VDOE formula sheet lists this formula for perimeter (p) of a rectangle.
Since all sides of a rectangle are not necessarily congruent as they are for squares we label the different sides as length(l) and width (w). Traditionally the longer side is referred to as the length and the shorter sides as the width but it doesn’t really matter as long as we have 2 congruent sides labeled (l) and 2 congruent sides labeled (w). The VDOE formula recognizes that there are 2 congruent sides labeled (l) top and bottom. And 2 congruent sides labeled (w) left and right sides. SO we can again use multiplication to calculate the perimeter. P = 2(l) + 2(w). If you prefer to add we can add p =l+l+w+w.
Using the VDOE formula, p = 2(8) + 2(3) we know we have to follow order of operations here so we first find both products then add them together.
2(8) + 2(3) becomes 16 + 6 which is 22 so p = 22 ft.
If you prefer addition then p = 8 + 8 + 3 + 3 or, p = 22 ft.
3 ft.
8 ft.
Perimeter Practice: (try these on your own using pencil and paper)- Find the perimeter of each square or rectangle:
(1) (2)
(3) (4)
4 in.
4 in.
7 cm.
7 cm.
3 yd.
5 yd.
3 yd.
10 yd.
Perimeter Practice Answers:
(1) p = 4(4) = 16 in. (2) p = 4(7) = 28 cm. or orp = 4+4+4+4 = 16 in. p = 7+7+7+7 = 28 cm.
(3) p = 2(5) + 2(3) (4) p = 2(10) + 2(3) p = 10 + 6 p = 20 + 6 p = 16 yd p = 26 yd.
or orp = 5+5+3+3 = 16 yd. p = 10+10+3+3 = 26 yd.
Area (A) of a rectangle is the number of square units it takes to fill or cover the rectangle. We would need to know the area of a rectangle if we were going to paint a wall or put carpet down on the floor. The area is represented by the grey area covering the rectangle.
Area (a)
We can think of the area of a rectangle as an array of rows and columns. We learned about arrays in 3rd grade when we began multiplying numbers. This rectangle is 3 units wide and 5 units long as shown in the array below.
3 units
5 units
We could count each square unit but that could take a while and we could make an error. A much more efficient way to determine how many square units are within the rectangle is to multiply the number of rows by the number of columns. 3 x 5 = 15 square units.
We can think about the above rectangle with a length (l) of 6 units and a width (w) of 2 units as having 2 rows and 6 columns. When we multiply the length (l) by the width (w) we get 12 square units as shown below.

The VDOE formula for finding the area (A) of a rectangle is A = lw.
In other words we simply multiply the length (l) by the width (w).
A = lw
Once again it doesn’t matter which side you choose to be the length and which side you choose to be the width because the Commutative Property of multiplication tells us that the order of the factors doesn’t change the product.Ex: 2x3 = 3x2.
Area (A) is ALWAYS reported in square units.
OK let’s do a few together:
2 ft.
5 ft.
3 cm.
8 cm.
A = lwA = 5(2)A = 10 sq. ft. or 10 ft.2
A = lwA = 8(3)A = 24 sq. cm. or 24 cm.2
Area Practice: (try these on your own using pencil and paper)- Find the area of each square or rectangle:

Area Practice Answers:(1) (2)
A = lwA = 4(4)A = 16 sq. in. or 16 in.2
(3) (4)
A = lwA = 7(7)A = 49 sq. cm. or 49 cm.2
A = lwA = 10(3)A = 30 sq. yd. or 30 yd.2
A = lwA = 5(3)A = 15 sq. yd. or 15 yd.2
The last thing to know for this module is that we may encounter Area or Perimeter problems in the form of word problems where we need to determine if area or perimeter will answer the problem and then apply the correct formula to get a solution. To help with this it is important to remember that:Area is how many square units it takes to cover a surface of a shape. _______________________And__________________________
Perimeter is the distance around the outside of a shape.
Lets try a few:Lisa is getting a new puppy and she wants to build a play area for him in her backyard. How much fencing will she need to build a fence around the area, if the play area is a rectangle, that is 8 feet wide and 12 feet long?
Thoughts: a fence goes around the outside so we need to find the perimeter. Two of the sides will be 8ft. and the other two will be 12 ft.
So p=2(l) + 2(w) or 2(12) + 2(8) 24 + 16 = 40 ft. Or we can add, 12+12+8+8 = 40ft.
She will need 40 feet of fence to go around the play area.
And another: James wants to build a wooden frame for his new family picture. The picture is 11 inches wide and 14 inches tall. How long will the piece of wood need to be for him to build the frame?
Thoughts: A frame goes around the outside of the picture so we need to find the perimeter.
So p=2(l) + 2(w) or 2(14) + 2(11) 28 + 22 = 50 in. Or we can add, 14+14+11+11 = 50in.
James will need a board 50 inches long to build the frame.
One more:Pamela wants to redo the floor in her hallway with tile. How much tile will she need to finish her hallway if the hallway is 3 feet wide and 12 feet long?
Thoughts: We need to cover the whole floor with tile so we need to find the area (how many square units fit in the hallway).
So area (A)= lw So we multiply the length(l) 12 by the width(w)3A = 12(3) A = 36 sq. ft. or 36 ft.2
Last One:Mike wants to stain his deck before summer. His deck is 24 feet long and 10 feet wide. A can of stain will cover 225 square feet of area. Will one can of stain be enough for him to stain his deck?
Thoughts he wants to stain or cover the entire deck so we need to find area. So A= lw A= 24(10) A= 240 sq. ft.240 > 225
One can of stain will not be enough to stain Mike’s deck because he needs to cover 240 square feet and one can only covers 225 square feet.

Module #1 Week 2Area and Perimeter of Triangles
SOL 6.7c) solve problems, including practical problems, involving area and perimeter of triangles and rectangles.
After completing this presentation you should be able to calculate the area (A) and Perimeter (p) of various triangles and understand when to use each measure when applied to practical (word) problems.
First let’s review some facts about triangles: - Triangles are 3 sided polygons- There are several classifications of triangles
but the formula used to calculate the area and perimeter of each type is the same.
Perimeter (p) is the distance around the outside of a shape or figure. We would need to know the perimeter if we were traveling in a straight line between 3 points or to put a border around a triangular shaped flower bed. The thick black line represents the perimeter of the triangle shown.
Perimeter (p) is the sum of all of the sides of a triangle. To find the perimeter of a given triangle we simply add the lengths of the three sides.
Therefore the perimeter (p) = 7 + 7 + 10 or p = 24 in.

(3) p = 6+7+11 (4) p = 7+7+4 p = 24 ft p = 18 in
Area (A) of a triangle is the number of square units it takes to fill or cover the triangle. We would need to know the area of a triangle if we were going to replace a broken pane of triangular glass, or cover a triangular yard in grass seed. The area is represented by the grey area covering the triangle.
Area
Interesting Note: We can think of a triangle as being ½ of a rectangle.
And since we already know how to find the Area (A) of a rectangle we can use those skills along with our note/observation above to help understand how to find the area of a triangle.
The VDOE formula for finding the area (A) of a triangle is: A = ½ bh.
But how does this relate to finding the area of a rectangle?
They simply renamed length and width as base(b) and height (h). And since a triangle is only ½ of a rectangle we then have to then multiply by ½.
Area (A) is ALWAYS reported in square units.
OK let’s do some together:In this example our base is 10 km and our height is 4 km. When we plug these values into the formula A = ½ bh we get :
A = ½(10)(4)A = (5)(4)A = 20 km2
*Hint: when using a calculator to multiply a number by ½ enter .5 instead. So on your calculator ½(10) would be .5(10)
Lets try another: In this example our base is 32 km and our height is 20 km. When we plug these values into the formula A = ½ bh we get :
A = ½(32)(20)A = (16)(20)A = 320 km2
One more together:In this example our base is 49 ft and our height is 46 ft. When we plug these values into the formula A = ½ bh we get :
A = ½(49)(46)A = (24.5)(46)A = 1127 ft2
Area Practice: (try these on your own using pencil and paper)- Find the area of each triangle:
(1) (2)
(3) (4)
Area Practice Answers:(1) A = ½ bh (2) A = ½ bh
A = ½(10)(8) A = ½(7)(10)A = (5)(8) A = (3.5)(10)A = 40 sq. in. or 40 in.2 A = 35 sq. yd. or 35 yd.2
(3) A = ½ bh (4) A = ½ bhA = ½(9)(4) A = ½(6)(5)A = (4.5)(4) A = (3)(5)A = 18 sq. ft. or 18 ft.2 A = 15 sq. ft. or 15 ft.2
The last thing to know for this module is that we may encounter Area or Perimeter problems in the form of word problems where we need to determine if area or perimeter will answer the problem and then apply the correct formula to get a solution. To help with this it is important to remember that:Area is how many square units it takes to cover a surface of a shape. _______________________And__________________________
Perimeter is the distance around the outside of a shape.
Let’s begin:
Sara is building a triangular corner shelf for her room. If the triangle shelf has a base of 24 inches and a height of 12 inches, How much wood will she need to build the shelf?
Thoughts: We need to build the whole shelf not just the outside so we need to find the area.
A= 1/2bh so: A = ½(24)(12)
A = 12(12)
A = 144 sq. In. or 144 in.2
Don’t forget, when using a calculator to multiply a number by ½ enter .5 instead. So on your calculator ½ (24) would be .5(24)
Sara will need 144 in.2 of wood to build her shelf.
And one more:
Jason walks 2 miles from his house to school. Then he walks 3 miles from school to the park. Finally he walks 5 miles back home. How far did Jason walk in all?
Home School
Park

5
3
Thoughts: we only need the distance on the outside of the triangle to calculate how far he walked so we need to find the perimeter
p = 2+3+5p = 10 miles
Jason walked 10 miles in all.
