Question:
The side of a square is 40cm and the breath of a rectangle is 20 cm . If their areas are equal then find the perimeter of the rectangle
Answer:
Given, area of the square = area of the rectangle
=> 40 = length*breadth
=> length*breadth = 40
=> length*20 = 40
=> length = 40/20
=> length = 2
Now, perimeter of the reactange = 2(length + breadth) = 2(2 + 20) = 2*22 = 44 cm
