Write an expression to represent the total cost of paint at a rate of $5.75 per ft.? to paint a triangular-shaped mural where the base of the triangle is 22 feet longer than the height

C($)= (x²/2 +11x)5.75

Step-by-step explanation:

Let's assume the height= x

The base= x+22

Area= 1/2(base*height).

Area= 1/2((x+22)(x))

Area= x²/2 +11x

Cost per ft= $5.75

Cost for painting the triangular mural C

C($)= (x²/2 +11x)5.75
