Answer 2

Hello Guys...

area of circle=196cm^2
side=√area=√196=14cm
the biggest circle is cut from the square
and the side of the square= diameter of the circle
so that the radius of circle =1/2of the side of the square
the radius of circle =14/2=7cm
area of circle=πr^2=22×7×7/7=22×7=154cm^2
area of the remaining place=area of square-area of circle=196-154=42cm^2

Thankyou.
