The dashed figure is a dilation of the original figure. Find the scale factor. Classify the dilation as an enlargement or a reduction.

To find the scale factor, we can compare corresponding side lengths of the original figure and the dashed figure.

Let's denote the original figure as figure A and the dashed figure as figure B.

Let's compare a side length of figure A and its corresponding side length in figure B:

Side length in figure A: 2 units
Corresponding side length in figure B: 4 units

Scale factor = Corresponding side length in figure B / Side length in figure A
Scale factor = 4 / 2 = 2

Since the scale factor is greater than 1, the dilation is classified as an enlargement.
