Answer 1

The scale factor is 5/4 = 1 1/4

Step-by-step explanation:

To find the scale factor, we use the ratio of the corresponding sides of new image against the old image.

We need an illustration as the diagram are orientated differently

From the diagram, the ratio becomes:

a/a = b/b

`\begin{gathered} \frac{a}{a\text{ }}=\text{ new figure/old figure} \\ a/a=(25/4)/(5)=(25)/(4)/5\text{ = }(25)/(4)*(1)/(5) \\ \frac{a}{a\text{ }}=(5)/(4) \end{gathered}`
`\begin{gathered} (b)/(b)\text{ = new figure/old figure} \\ (b)/(b)\text{ = }\frac{15}{12\text{ }}=(5)/(4) \end{gathered}`

Since a/a = b/b = 5/4

The scale factor is 5/4 = 1 1/4
