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 9 inches longer than the width, we can express the length as l = w + 9. Substituting this into the perimeter formula gives us 62 = 2(w + 9) + 2w, which simplifies to 62 = 4w + 18. Solving for w, we get w = 11 inches.
