Question

the length of a rectangular plot is 1.5 times its breadth 20% of its perimeter is 20 metres the area of the plot is

Answer 1

Let length of plot = L meters, then breadth = L - 20 meters

and perimeter = 2[L + L - 20] = [4L - 40] meters

[4L - 40]  * 26.50 = 5300

[4L - 40] = 5300 / 26.50 = 200

4L = 240

L = 240/4= 60 meters.
