63 inches
Explanation:
The perimeter of a rectangle is found by adding all of the side lengths. Since both pairs of opposite sides have the same length, an equation for the perimeter can be written like this:

Where w and l represent the width and length.
Since we are asked to find the length, rewrite the equation in terms of l:

We know the values for P and w, so plug those in:

Now simplify!
