You can
put this solution on YOUR website!since perimeter = 2 times the length +2 times the width
:
2L+2W=P......2L+2W=36....there is an infinite amount of solutions....if you looking for some examples just plug in any number for either variable and solve for the other.
:
such as

....2(1)+2W=36....2W=34...

or

2(4)+2W=36...2W=28...
this can go on forever...
