Question

The perimeter of square is 36 cm and breadth of rectangle is 7 cm. if the perimeter of square and rectangle are equal then the area in square cm of the rectangle is?

Answer 1

Perimeter of square =perimeter of rectangle

$4 \times side = 2(l + b)$
36=2(l+7)
36=2l+14
2l=36-14
l=22/2
l=11cm
Area of rectangle =l*b
=11*7

$77 {cm}^{2}$
Thank You.
