the diagram shows the floor plan of a storage facility. all dimensions are given in feet. which expression represents the area of the storage facility in Square feet? L:5x + 4 , W:4x - 4
20x^2 + 36x - 16
20x^2 - 4x - 16
16x^2 - 16
9x^2 - 16
The area of a rectangle is given by multiplying its length by its width.
Area = L x W
Area = (5x + 4)(4x - 4)
Area = 20x^2 + 20x - 16x - 16
Area = 20x^2 + 4x - 16
So, the expression that represents the area of the storage facility in square feet is 20x^2 + 4x - 16.
