total distance of 210m. If the chain was correct before the commencement of
chaining, find the true distance.
Q4. The plan of an old survey plotted to a scale of 10m to 1cm was found to
have shrunk so that a line originally 10cm long was found to measure 9.8cm.
There was also a note on the plan that the 30m chain used in the survey was
0.03m too short. If the area of the plan measured now with a planimeter is
96.04 cm2, determine the true area of the survey.
