 Question 246659: the perimeter of a rectangle is 56 cm. The width is 6 cm less than the length. Find the width and the length.Answer by rapaljer(4667)   (Show Source): You can put this solution on YOUR website!Let x= length (because this is the last phrase in the first sentence!) x-6 = width 2W + 2L = Perimeter 2(x-6) +2(x)= 56 2x-12+2x=56 4x-12=56 Add +12 to each side: 4x-12+12=56+12 4x=68 x=17 Length x-6=11 Width Check: 2*17+2*11 34+22 56 It checks!!

From the Homepage of my website, look for the link "Basic, Intermediate, and College Algebra: One Step at a Time." Choose "Basic Algebra", and look in "Chapter 1" for "Section 1.10 Word Problems." Here I have tried to give a non-traditional explanation designed for students who have trouble with math. My own students have unanimously told me that they understood MY explanations a LOT better than traditional textbooks! On this topic, I have quite a lot of the exercises solved IN COLOR on my "MATH IN LIVING COLOR" pages that accompany my explanations. Try it, and see if it works for you.
