Can someone me out with this n you

The answer to your question is: A = 25.12 ft²

Step-by-step explanation:

Data

Width = 8 ft

Length = 10 ft

Area of the rectangle = base x length

Area of the circle = πr²

Process

Area of the rectangle = 10 x 8 = 80 ft²                  Substitution

Area of the semicircle = (3.14 x 4²) / 2

                                     = 25.12 ft²

Total area = A rectangle + A semicircle

                 = 80 + 25.12

                 =  105.12 ft²
