Doing math homework and this question with an unfamiliar concept appears. It says: "Dilate a triangle with vertices (0, 0) , (0, 2) , and (2, 0) using the scale factor k=3 . What is the value of the ratio (new to original) of the perimeters? the areas?"
There are two type-your-answer-here boxes, one of which is: "The ratio of the perimeters is (box)." I typed 3, because it made sense. That was correct. But the other answer-here was rather confusing. "The ratio of the areas is (box)." I've been stuck for a bit now and am looking for some help. I have attached a screenshot of the problem, if that helps :)
