Answer:
257.1 cm²
Explanation:
Parallelogram,
Base = 16 cm
Height = 9 cm
Area of Parallelogram = Base x Height
A = 16 x 9
A = 144 cm²
Area of SemiCircle = 1/2 x πr²
Radius = Diameter/2
Radius in this question = 12/2
Radius of both semi circles = 6cm
Area of Semi circle 1 = Area of Semi circle 2
SemiCircle 1 and SemiCircle 2 Area = 1/2 x π(6)²
= 56.54cm² (each SemiCircle)
Both SemiCircles area combined = 56.54 x 2
=113.08 cm²
Area of the whole figure = Area of Parallelogram + Area of both SemiCircles combined
Area of whole figure = 144 + 113.08
= 257.08 cm²
Rounded of to the nearest tenth = 257.1 cm²
