Question 74621
Let x=width
Then 2x+3=length

Perimeter(P)=2L+2W ---So our equation to solve is:

36=2(2x+3)+2x  get rid of parens

36=4x+6+2x  collect like terms

36=6x+6  subtract 6 from both sides

6x+6-6=36-6
6x=30  divide both sides by 6
x=5 in------------------------------------width
2x+3=2*5+3=13 in-------------------------------length

CK
36=2*5+2*13
36=10+26
36=36

Hope this helps----ptaylor
