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 poo-poo head, depending on how you interpret this problem, there are different answers.

anonymous · Answer

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|
