The area of a rectangular room is 750 square feet. The width of the room is 5 feet less than the length of the room. Which equations can be used to solve for y, the length of the room?

The formula for the area of any rectangle is:

Area=Length x Width

750=y (y-5)

750=y square-5y

Rotate this equation.

y square-5y=750

y square-5y=750

Let's factorize:

y (y-5) = 750

Two potentially true values of y can be y=750 or y=750-5=745

y=745 ft. Answer.
