Answer: 138.63 mm²

Step-by-step explanation:

    First, we will solve for the area of the rectangle.

A = L * W

A = 15 mm * 5 mm

A = 75 mm²

      Next, we will solve for the area of the semi-circles. Since there are two equivalent semi-circles, I will find the area of one circle with the same radius as these two.

      First, we need to find the radius.

15 mm - 3 mm - 3mm = 9mm, 9 mm / 2 = 4.5 mm

A = πr²

A = π(4.5)²

A ≈ 63.62 mm²

      Lastly, we will add them together.

75 mm² + 63.62 mm² = 138.63 mm²
