Question

find the area of a rectangle whose breadth is 7 metre and its perimeter is equal that of a square with side 12 metre?​

Answer 1

Perimeter of square = 12x 4 = 36

Let the other side of the rectangle the be x

(x+7)2 = 36

2x = 31

x = 15.5 m

Area = length X breadth

7x 15.5 = 108.5m square
