Question

find the area of a square whose perimeter is equal to the perimeter of a rectangle whose side length and breadth is 30 cm and 20 CM respectively​

Answer 1

Given length and breadth of a rectangle are 30 and 20cm respectively

perimeter of rectangle=2(30+20)

=2(50)

=100m

perimeter of square=4s=100

s=100/4

s=25

Area of square=s^2

=25x25=625
