Answer:
Area of square = s×s
s = 7 cm.
7×7 = 49 sq. cm
Area of circle = pi r sq.
if diameter = 7 cm. then radius = 3.5 cm.
the area of semi - circle = 1/2 pi r sq.
1/2 × 22/7 × 3.5 × 3.5
= 1/2×22×0.5×3.5
11×0.5×3.5
= 19.25 sq. cm
Area of shaded region = area of square + area of semi-circle
49 + 19.25
= 68.25 sq. cm
