For braibliest answer
quadrilateral a’b’c’d’ is a dilation of quadrilateral abcd about point p with a scale factor of 2 1/2

is the dilation a reduction or an enlargement?

a. reduction
b. enlargement

Hi, friend.
The answer to your question is B) Enlargement.
Hope this helps you!

It would be an enlargement because the rule is when a dilation is 1 and up, it means it gets larger. And of course when the scale factor is less than 1, it's simply a reduction.
Because the scale factor is 2.5, it gives you the answer B. enlargement.
Hope this helps!:)
