Question

Enter the scale factor applied to Figure A to produce Figure B

Answer 1

$\begin{gathered} \text{ Since they must be proportional, that is} \\ 9=r\cdot22.5\text{ and 11=r}\cdot27.5 \\ where\text{ r is the scale factor, thus } \\ r=\frac{22.5}{9}=2.5 \\ \\ \text{and the scale factor is 2.5} \end{gathered}$
