A square and a rectangle have the same perimeter. If the length and breadth of the rectangle are 25 cm and 15 cm respectively, find the side of the square.

Given: Perimeter of square and rectangle is same. For rectangle L=25 cm, B = 15 cm

To find : Side of square

Solution:

Perimeter of rectangle = 2 (length + breadth)

= 2(25 + 15)  = 2(40)  = 80 cm

Perimeter of square = Perimeter of rectangle

We know Perimeter of square = $4\times side$

$4\times side$ = 80 cm

⇒ side = 80/4

= 20 cm
