Question

If the perimeter of a circle is equal to that of a square, then the ratio of their
areas is
A 22.7.

B. 14.11
22​

Answer 1

perimeter of square = circumference of circle

4a = 2πr

a = (πr)/2

according to the question

a² = πr²

[(πr²)/2]² = πr²

therefore

on cancelling

we get (πr²)/4
