What, exactly, is tripled? Not trying to be a poo-poo head, depending on how you interpret this problem, there are different answers.
the perimeter of the rectangle
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|
Would it be 30?
Why do you say 30?
You got it. :)
Great! Thanks so much
