11 inches wide.

Explanation:

The formula for perimeter is 2(l)+2(w). If we substitute l for 14, we get 28 for the total length of both l's. In order to find 2w, you must subtract 28 from 50, which is 22. Since this 2w, and we're looking for w alone, you have to divide by two. 22/2=11, which means that each width is 11 inches.
