Problema Solution

The length of a rectangular jewelry box is 5 inches more than twice the width. The perimeter is 46 inches. Find the length and width.

Answer provided by our tutors

let 'w' represent the width in inches, then '2w+5' represents the length


perimeter = 2(length+width)


46 = 2(w+2w+5)

46 = 6w+10

36 = 6w

w = 6


2*6+5 = 17


the jewelry box is 6 inches wide and 17 inches long
