Question

The areas of a square and a rectangle are equal. If the side of the square is $18cm$ and the length of the rectangle is $36cm$, find the breadth of rectangle. Also, find the perimeter of the rectangle (in cm).

Answer 1

let the breadth of rectangle be $x$.

area of square = area of rectangle

$18\times 18=x\times 36$

$x=9$

perimeter$=2(l+b)$

$=2(9+36)$

$=90cm$
