A rectangular closet is three dimensional. It also has depth. Are you just considering the door to the closet?
W = L/2 - 1
2W + 2L = 40
Substitute L/2 - 1 for W in the second equation and solve for L. Insert that value into the first equation to solve for W. Check by putting both values into the second equation.
if the perimeter of a rectangular closet is 40 ft and the width is 1 ft less than half of the length, what are the length and width ?
