Answer:
Area of square = side × side
= 7 × 7
= 49 cm²
Area of semi circle = ½ × πr²
= ½ × 22/7 × 3.5 3.5
= 19.25 cm²
Total area = 49 + 19.25
= 64.25 cm²

Answer:
Total Area will be 68.25 cm²
-----------------------------------------------------------
Area of square = Side× Side
= 7×7
= 49 cm ²
Area of semicircle = πr²/2
= 22/7×3.5×3.5 × 1/2
= 77/2× 1/2
= 77/4
= 19.25 cm² (Radius = D/2 = 7/2 = 3.5cm)
Total Area = 49+19.25 = 68.25 cm²
