Quizplus · Accepted Answer

The perimeter of a rectangle is given by the formula $2l + 2w$, where $l$ is the length and $w$ is the width. Given that the length is 6 inches longer than the width, we can express the length as $l = w + 6$. Substituting this into the perimeter formula gives $2(w + 6) + 2w = 56$. Simplifying, $4w + 12 = 56$, and further $4w = 44$, leading to $w = 11$ inches.
