Answer:

Given : The perimeter of a circle is equal to twice that of square,  

To Find :     ratio of their areas is: -

Solution:

Radius of circle  =  r

Side of square = a

Perimeter of circle =2πr

Perimeter of square = 4a

2πr = 2 * 4a

=> r = 4a/π

Area of circle  = πr²  = π(4a/π)²  = 16 a²/π

Area of  square = a²

Ratio  =  16 /π

16/(22/7)

= 7 * 16 /22

= 56/11

ratio of their areas is: -  56/11​
