Answer:
The answer to your question is: area = 105.12 ft2
Explanation:
Here we have to figures, a rectangle and a semicircle, then we calcule the areas of each figure and after we add them.
Area of a rectangle
area = base x height
area = 10 ft x 8 ft
area = 80 ft2
Area of a circle
area = πr2 = 3.14 x (4 ft)2
area = 3.14 x 16 = 50.24 and we divided by 2 because is a semicircle
area = 50.24/2 = 25.12 ft2
Total area = 80 + 25.12 = 105.12 ft2
