Answer:
31.7 units²
Explanation:
Since the two semicircles have the same radius, they have the same combined area as a full circle.
Rectangle: length 10; width 6
Circle: diameter 6; radius 3
area = area of rectangle - area of circle
area = LW - πr²
area = 10 × 6 - 3.14159 × 3²
area = 60 - 28.27431
area = 31.72569
Answer: 31.7 units²
