Question

the area of s square is the same as the area of the circle.Their perimeters are in ratio a)1:1 b)2:π c)π:2 d)√π:2​

Answer 1

Solution :

Let the radius of the circle be r and the side of the square be a.

Then according to the question, πr2=a2=>a=rπ√

(i) Now , Ratio of their perimeters =2πr4a

Ratio of their perimeters =πr2a

=πr2rπ√

=π−−√2

Ratio of their perimeters =π√:2

(d)
