Question 209992
Let x = width of the rectangle
x+5 = length 


2W + 2L = P


2(x) + 2(x+5) = 58

2x+2x+10 = 58
4x+10=58
4x = 48
x=12  width
x+5 = 12+5=17 length


Check:  

2*12+2*17
24+34= 58 = Perimeter


For additional explanation on solving Word Problems please see my website by clicking on my tutor name "Rapaljer" anywhere in algebra.com.  On my homepage, look for the link "Basic, Intermediate, and College Algebra: One Step at a Time."  Go to "Basic Algebra", and look for "Chapter 1" and select the sections marked "Word Problems."
