Let l represent length, and w represent width l=3w-5
P=2(l+w) 46=2(l+w) Divided 2 for both side l+w=23 Now, I substitute l=3w-5 into this equation 3w-5+w=23 4w-5=23 Add 5 for both side 4w=28 Divided 4 for both side w=7 inches l=3w-5 l=3(7)-5 l=21-5 l=16 inches. As a result, the length is 16 inches, and the width is 7 inches. Hope it help!
