Side of square = 21 cm
Radius of greatest circle inscribed inside the square = 21/2 cm
Area of circle = πr²
=22/7×21/2×21/2
=346.5 cm²
Radius of greatest circle inscribed inside the square = 21/2 cm
Area of circle = πr²
=22/7×21/2×21/2
=346.5 cm²

Hey there !!!!!
The greatest circle which can be inscribed inside the square will be a circle whose diameter = side of the square.
∴ diameter =21 and radius =21/2
Area of circle =πr²
=π*(21/2)²
=3.14*110.25 = 346.5 cm²
Hope this helps you ................
