Question

How do i solve for scale factor from smaller to larger?

Answer 1

1) k = 3

2) k = 2

Step-by-step explanation:

To find the scale factor from the smaller to the larger figure, we need to divide the length of the larger figure by the length of the smaller figure.

The figures are similar, so we will use corresponding sides. Then:

`\begin{gathered} k=\frac{\text{ larger length}}{\text{ smaller length}} \\ \text{ For the first figure:} \\ k=(21)/(7)=3 \\ \text{For the second figure:} \\ k=(8)/(4)=2 \end{gathered}`

Therefore, the answers are:

1) k = 3

2) k = 2
