Solution

Find the scale factor.
Given, figure
From the given figure, we can have
$A B = 1$ unit and $A' B' = 2$ units.
Since we know scale factor = $\frac{s i d e l e n g t h o f i m a g e f i g u r e}{s i d e l e n g t h o f a c t u a l f i g u r e}$
So, the scale factor will be $\frac{2}{1} = 2$ .
We can see from the above figure that the size of the image is larger than the size of the original image. So, it is the enlargement dilation.
Hence, the scale factor is $2$ and the type of dilation is enlargement.
