Too typical.

b for breadth, given;
L for length, given;
w for uniform width of path, unknown.
Let P = the area of the walkway around the rectangular pool, given.

Area of whole region minus area of the pool equals area of just the walkway path.

ONLY ONE variable is unknown, and it is w. Simplify the equation and solve for w. This should be uncomplicated, as it is a quadratic equation. You would either finish through factoring or through using the general solution of a quadratic equation.
