Given,
side of square =14cm
Area of larger Square =side
2
=14
2
=196cm
2
There are four semi circle that means we have two complete circles of diameter of 2xcm
then we can observe that
3+x+2x+x+3=14
i.e., x=2
so radius of circle is 2cm
Area of non shaded region=area of two circle + area of square of side 4cm
= 2.pi.r
2
+side
2
= 25.12+16
= 41.12cm

Hence,
Required area of shaded region =196−41.12=154.88cm
