Question

the square defg is a dilation of the square defg. what is the scale factor of the dilation?
simplify your answer and write it as a proper fraction, an improper fraction, or a whole number.

Explanation:

Step1: Identify side lengths of squares

Side length of DEFG: $6 - 3 = 2$
Side length of D'E'F'G': $10 - 5 = 5$

Step2: Calculate scale factor

Scale factor = $\frac{\text{Image side length}}{\text{Pre-image side length}}$
$\text{Scale factor} = \frac{5}{2}$

Answer:

$\frac{5}{2}$
