Question

the area of rectangle is same as the area of square of side 15 cm. if the breadth of the rectangle is 10 cm then find the perimeter of rectangle.

Answer 1

Area of Rectangle = Area of square
l × b = side^2
l × 10 = (15)^2
l = 225/10
l = 22.5
Perimeter of Rectangle = 2(l+b) = 2(22.5 + 10)
= 2 × 32.5
= 65cm^2
