Answer:
Enlargement
Step-by-step explanation:
Dilation is the enlargement or the reduction in the size of an object.
Enlargement is increase in size of an object. A figure is said to be enlarge if it is larger than the original figure.
Reduction is the decrease in size of an object. A figure is said to be reduced if it is smaller than the original figure.
The scale factor determines if it is either an enlargement or a reduction. If the scale factor is less than one then it is a reduction whereas if the scale factor is greater than 1 it is an enlargement.
Since it is a scale factor of 5/2, it is an enlargement.
