Question

figure e is dilated to form figure f. what is the scale factor of the dilation? scale factor =

Explanation:

Step1: Measure side - lengths

Let's assume the side - length of square $E$ is $1$ unit (by counting the grid squares). The side - length of square $F$ is $2$ units.

Step2: Calculate scale factor

The scale factor $k$ of a dilation is given by the ratio of the corresponding side - lengths of the dilated figure ($F$) to the original figure ($E$). So, $k=\frac{\text{side - length of }F}{\text{side - length of }E}$.
$k = \frac{2}{1}=2$

Answer:

$2$
