Best ResponseYou've already chosen the best response.1The dimensions are not the perimeter. The dimensions mean "the length and the width". So if the length is say, 4 and the width is 1, then the perimeter is 4 + 4 + 1 + 1 dw:1341673430917:dw

Best ResponseYou've already chosen the best response.1Now if you triple the dimensions, that means you triple the length and triple the width... 12 + 12 + 3 + 3 dw:1341673481562:dw
