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 7 inches longer than the width, we can express the length as l = w + 7. Substituting this into the perimeter formula gives us 58 = 2(w + 7) + 2w. Simplifying, we get 58 = 4w + 14, leading to 44 = 4w, and thus w = 11 inches.
