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.
