Which three sides?

Doing the beginning of this ALL IN VARIABLES, let patio dimensions be x and y. A is flower bed area, and u is uniform width of bed around the three sides of the patio. Depending on which dimension SIDES receive part of the flower bed, usage of the variables into expression may go as...

system%28%28x%2B2u%29%28y%2Bu%29-xy=A%2C+OR%2C+%28x%2Bu%29%28y%2B2u%29-xy=A%29

Pick the one which corresponds to how you choose your variable assignments and solve for u.
