You can put this solution on YOUR website!
324%2F2=162, so if L=162 and W=2 then P=2%28L%2BW%29=328
324%2F4=81, so if L=81 and W=4 then P=2%28L%2BW%29=170
324%2F6=54, so if L=54 and W=2 then P=2%28L%2BW%29=120
324%2F12=27, so if L=27 and W=12 then P=2%28L%2BW%29=78
324%2F18=18, so if L=18 and W=18 then P=2%28L%2BW%29=highlight%2872%29
cant get any lower peremeter then that
