Area of a Trapezoid

legleg

b1 = base 1

b2 = base 2

h = height

Height – the perpendicular distance between the 2 bases.

A = ½ h(b1 + b2)Area of trapezoid

Example 1

Area of a Kite or Rhombus

Rhombus› 4 equal sides.› Diagonals bisect

each other.› Diagonals are

perpendicular.

Kite› Adjacent sides are

congruent› No sides //.› Diagonals are

perpendicular
