Answer:
D. 3
Step-by-step explanation:
Hey there!
Lets review the information given in this question.
First of all, she decides to enlarge it by a scale factor of three
We also know that one side of the original is 1 inch.
So, first of all, it says by a factor of 3. The first step and only step is to times 3 by 1. The answer is obviously 3.
How did we get 3? well, it had a factor of 3. it could be 3, 6, 9. but the most reasonable answer is 3. And the length of one of the original side was 1.
Therefore, we needed to multiply 1x3.
I hope this helps you :)
