The formula for the perimeter of a rectangle is incorrect in the question. The correct formula is $P = 2l + 2w$, where $P$ is the perimeter, $l$ is the length, and $w$ is the width. Given $P = 40$ feet and $l = 14$ feet, we can solve for $w$ as follows: $40 = 2(14) + 2w$, simplifying to $40 = 28 + 2w$, and then $12 = 2w$. Solving for $w$, we get $w = 6$ feet.
