Question

If the area of a square is same as the area of a circle. find the ratio of theperimeter of the square and that of the circle.​

Answer 1

let the side of square be s

area of sq=a sq unit

let the radius of circle be r.

so,area of circle=(pie×r sq)sq unit.

a²=22/7×r² on sq rooting both sides.

a/r=√22/7.

so let a be √22X and r be √7 X

so there perimeter ratio.

ratio=. 4×s/2×3.14×r

= 4√22/2×3.14×√7

= 16×22/4×3.14×7 ×3.14

=1/11
