If the perimeter of a circle is equal to that of square, then the ratio of their areas is:
The correct option is B: 14:11
Let the radius of the circle be r and side of square be a.
According to the given condition,
The perimeter of a circle = Perimeter of a square [Given]
Now, Area of circleArea of square=πr2(a)2
=πr2(πr2)2 [Using eq.(i)]
