To find area of shaded region = Area of square - ( Area of region 1+2+3)
Area of square = side×side
according to the diagram side of square is 7+7=14cm
Area of square= 14×14 =196cmsq
Area of region 1: area of semi circle=1/2 πr^2
r=7cm
=1/2 × 22/7 (7×7)
= 77 sqcm
Area of region 2: quadrant of circle= 1/4 πr^2
1/4× 22/7 (7×7)
=38.5 sqcm
area of region 2= area of region 3
= 38.5 sqcm
shaded part= 196 - ( 77+38.5+38.5)
= 196- 154
=42 sqcm
