Assuming the rectangle is 10 by 8, the figure’s area = rectangle area + area of semicircle with diameter 10 − area of semicircle with diameter 8.
Rectangle: 10·8 = 80
Semicircle (d = 10, r = 5): (1/2)π(5^2) = 12.5π
Semicircle removed (d = 8, r = 4): (1/2)π(4^2) = 8π
Total area = 80 + 12.5π − 8π = 80 + 4.5π ≈ 80 + 14.137 = 94.1
Answer: 94.1 square units (to the nearest tenth).
