Quizplus · Accepted Answer

The perimeter of a rectangle is given by the formula $P = 2l + 2w$, where $l$ is the length and $w$ is the width. Given that the length is 14 inches longer than the width, we can express the length as $l = w + 14$. Substituting the given perimeter and the expression for $l$ into the perimeter formula gives $64 = 2(w + 14) + 2w$. Simplifying, we find $w = 9$ inches.
