Question

Two plots of land have the same perimeter what is a square of side 64 M and the other is a rectangle of length 70 M find the breadth of rectangle rectangular plot which plot has the greater area and by how much

Answer 1

Perimeter of Square = 4l

= 4×64

= 256 M

As perimeter of both are equal:

Perimeter of Rectangle = 2(l+b)

256 =2(70+ b)

256 =140+2b

256-140 = 2b

116 = 2b

116/2 = b

b = 58 M
