Do you know what the phrase "Dimensions are tripled" means? (like, can you draw a before and after picture)

What, exactly, is tripled? Not trying to be a poopoo head, depending on how you interpret this problem, there are different answers.

The 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

Now if you triple the dimensions, that means you triple the length and triple the width... 12 + 12 + 3 + 3 dw:1341673481562:dw
