The area of a square is the same as the area of a circle. Their perimeters are in the ratio

Let the length of the side of the square be a


Let the radius if circle be r


Area of a square = a2


Area of circle = πr2


Area of a square = Area of a circle


a2 = πr2


a = √π × r


Perimeter of circle = 2πr


Perimeter of square = 4a


= 4√π r




Ratio of perimeter of circle and square = √π : 2
