Answer:
2.5
Explanation:
To know the scale factor applied to figure A, we need to divide the length of one side of figure B by its corresponding side on figure A. So, dividing 22.5 by 9, we get:
[tex]\text{scale factor = }\frac{22.5}{9}=2.5[/tex]Therefore, the scale factor applied to figure A to produce figure B is 2.5
