Question

the area of a square and a rectangle are equal if the side of the square is 40 cm and the breadth of the rectangle is 25 cm find the length of the rectangle

Answer 1

Area of square = 402=1600

Area of rectangle = 25∗L where L is the length of the rectangle.

Since area of square and rectangle are same, 25∗L=1600=25∗64

Hence L=64

Perimeter of rectangle = 2L+2B=2∗64+2∗25=128+50=178cm
