20 because of the whole is 40 and the shaded part is by 20 you just take half of 40 and you get 20
We can solve by figuring the area of the rectangle then add it to the area of the semicircle.
Area of the rectangle: length · width = 6 · 10 = 60 ft²
Area of the semicircle: (πd²)/8 = (3.14 · 6²)/8 = (3.14 · 36)/8 = 14.13 ft²
Total area of the figure: 60 + 14.13 = 74.13 ft² ≈ 74 ft²
Assuming it's 7, 2, and 31, you can set up (31+7)/2 is the amount that Carlos scored, which is 38/2 or 19.
The answer is 76.99 but rounded would make it 77.00 which is C
