Solve "if the perimeter of a circle is equal to that of a square, then the ratio of their area is"

Answer 1

HELLO MATE!!! ✌

HERE IS YOUR ANSWER:-

Given, the perimeter of circle is equal to that of square.

Thus, 2πr = 4a---->a= 2πr/4=πr/2

Now, ratio of their areas= πr²/a²

= πr²/(πr/2) ²

= πr² × 4 / π²r²

= 4/π

= 4/22/7

= 4×7/22

= 28/22

=14/11

Ratio:- 14:11
