Question

What scale factor was applied to the first rectangle to get the resulting image?

Enter your answer as a decimal in the box.

Answer 1

7.5/3=2.5 is the correct answer

Answer 2

`2.5`

Explanation:

we know that

The scale factor is equal to the length side of the resulting image divided by the length side of the original image

so

`scale\ factor=(7.5)/(3)=2.5`

`2.5 > 1` -----> the scale factor is greater than
`1` (because is an enlargement)
