What's the answer to this?

Answer: 4
Step-by-step explanation:
First, we will find the length of sides TU and T'U' to compare. Then, we will find the scale factor. Since the shape gets bigger and not smaller, we will have a whole number - not a fraction.
TU = 3 units
T'U' = 12 units
12 / 3 = 4
A scale factor of four.
