If 15 and 21 work, what is L and W?

Solve this equations for L and W, where P is the perimeter (14, 15, 20) or any value ≥ 13.86:

L = [P ± √(P² - 2 * 4 * 24)]/4

Use the + choice in ± for L, it is usually longer. W will then be the - choice.

For example, with P = 14, L=4, W=3. With P=15, L=5.19, W=2.31. With P=20, L=8.6, W=1.39.
