Not like P=2w+2l because it is not visually understood without extended effort. Call the length, L.

You have some general situation, L=w+d and 2w+2L=P for positive real numbers d, P; and the unknown variables are L and w.

, and you already have assigned d=3 and P=26.

-
Use the formula given for L:

Just substitute the values for d and P to get the values for w and L.
