Answer :

Given:

Perimeter of square = Circumference of circle ………………. (i)

Area of Square = 484m2

Let the side of square be ‘x’ cm.

Area of Square = side × side

484 = x × x

x2 = 484

x = √484 = 22cm

Perimeter of square = 4 × side

= 4 × 22 = 88 cm

Using (i), we have

Circumference of circle = 88 cm

Also, Circumference of Circle = 2πr

2πr = 88

2 × × r = 88

r = 88 × × r = 2 × 7 = 14 cm

Area of Circle = πr2 = × 14 × 14

= 22 × 2 × 14 = 616 cm2

Hence, the area of Circle is 616 cm2.
