Question

now, find the scale factor.
side length in original rectangle corresponding side length in scaled copy
1 3
2 6
the scale factor is

Explanation:

Step1: Recall scale - factor formula

The scale factor $k$ is given by $\frac{\text{side length in scaled copy}}{\text{side length in original}}$.

Step2: Use first row data

For the first row, with side length in original $a = 1$ and side length in scaled copy $b = 3$, $k=\frac{b}{a}=\frac{3}{1}=3$.

Step3: Check with second row data

For the second row, side length in original $a = 2$ and side length in scaled copy $b = 6$, $k=\frac{b}{a}=\frac{6}{2}=3$.
