Step-by-step answer:

Given an enlargement from preimage (ABC) to image (A'B'C').

Need to find scale factor.

Solution:

Scale factor = linear size of image / linear size of preimage.

From the accompanying diagram, we see that

L(preimage) = AC = 4 units

L(image) = A'C' = 12 units

Therefore

Scale factor = L(image) / L(preimage) = 12 / 4 = 3
