Answer: enlargement
Step-by-step explanation:
A dilation is a transformation which stretches or shrinks the original shape.
It creates similar shapes but of different size.
If the scale factor is greater than 1 then the image is an a stretch or enlarged.
If the scale factor is between 0 and 1 then the image is a reduction or a shrink.
If the scale factor is 1 then the figure and the image are congruent.
The given scale factor is [tex]2\frac{1}{2}[/tex]
Since [tex]2\frac{1}{2}[/tex] >1 .
Therefore, the dilation is enlargement .
