Question

Stupid online math summer school crap my mom signed me up for. I really hate her sometimes.
Triangle L'M'N' is the image of triangle LMN after the dilation.

Which statement explains how to find the coordinates and the area of Triangle L'M'N'?

Answer 1

Divide each of the vertices of triangle LMN by 3 to find the coordinates. To find the area of triangle L'M'N', compute the area of triangle LMN and multiply by 9.

Answer 3

Sorta like that.

If you enlarge, you would multiply x-coordinate and y-coordinate by for example 3.

So to find area, you have both x-coordinate and y-coordinate to consider into.


I am bad at explaining, but hope that clear up a little bit.
