The ratio of area of two square circumscribe and inscribe by a circle is

For a square inscribing the circle,
Diagonal of the square = diameter of the circle
Let the radius of the circle be r
⇒ Diagonal of the circle = 2r
We know that the diagonal of the square = √2 side
⇒√2 side = 2r
⇒Side of the inscribed circle = √2r
Area of the inscribed square = side× side
⇒ Area of the inscribed circle = 2r2

For a square circumscribing the circle,
Side of the square = diameter of the circle
⇒ Side of the circumscribed circle = 2r
Area of the circumscribed square = side× side
⇒Area of the circumscribed circle = 4r2
