Question 156649
Once you know the rules you can break them!  In algebra, start with the formula.  the formula for a perimeter is P=2(w + l).  I don't have a conventional way of solving for the perimeter but this does work.  The perimeter of the rectangle is 60 inches.  The first thing is do is divide by four.60/4=15.  now, if this perimeter is 15 on all sides, that's not a rectangle, thats a square!  But remember, the length is 4 inches longer than the width.  Add 2 inches to two sides 15 + 2 =17.  Now take two from the other side15-2=13.  Check your answer 17-4=13. And double check by substituting values:  P = 2(17+13) P=34+26 P=60
