Answer: 44.7 units²
Explanation:
First, we will find the area of the rectangle.
A = LW
A = (8 units)(4 units)
A = 32 units²
Next, we will find the area of the circle. We have two semicircles which is equal to one circle. The radius is half of the width of the circle (which is the diameter). The diameter here is 4, so the radius is 2.
A = πr²
A = π(2 units)²
A ≈ 12.566 units²
Next, we will add these pieces together.
A = 32 units² + 12.566 units² = 44.566 units²
Lastly, we will round to the nearest tenth.
44.566 units² ≈ 44.7 units²
