Step-by-step explanation:
not sure what level you are in at school. Since the dilation is about the origin, it very straight forward. Basically you multiply the scale factor by each coordinate of a given point.
so the dilated point for A is in the x direction 1x6 and in the y direction 2x6, resulting in A'= (6,12).
do this for each point and you will have the answer
