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.
