A local school needs to paint the floor of its theater room, where the length of the floor, x, is at least 12 feet. The width of the floor is 4 feet less than the length. It will have a stage and a closet, and the remaining area of the floor will be painted. The dimensions are shown in the diagram: Let A represent the painted area, in square feet, of the floor. Choose the correct equation to solve for area (A).

A = x(x − 4) − 0.5(8)(x − 4) − 4(8)

A = x(x − 4) − (8)(x − 4) − 4(8)

A = x(x − 4) + (8)(x − 4) + 4(8)

A = x(x − 4) + 0.5(8)(x − 4) + 4(8)
