Answer 1

Answer:

Step-by-step explanation:

Let us solve for the total area. In this problem, we solve area 1 (the rectangle in the middle) and the area 2 ( the two half circle on the sides).

Solve for area 1:

Area rec = L * W = 5units * 4 units = 20 squared units

Solve for area 2:

Area cir = pi *r² = 3.14 * (2 units)² = 12.56 squared units

Total area = 20 + 12.56 = 32.56 foot²

Total cost = 32.56 foot² * ($23/foot²) = $ 748.88

Total cost is $748.88.
