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.
