10 x 4 = 40

Radius is 10/2 = 5

5^{2}π/2 = 12.5π

5 + 12.5π ≈ 44

Your answer is A

Ok so we first find the area of the rectangle. 10m^2 * 4m^2 = 40m^2

Then we find the area of the semicircle. Since we know the diameter is 10, the radius is 5. To find the area of a semicircle we use the equation\(\frac{1}{2}(\pi r^2)\). 1/2 (pi * 5^2)\(\approx\)40

40+5=45 so the answer is a

edit. yeah. what logarhythm said.
