Answer:
A. [tex] \frac{1}{5} [/tex]
Step-by-step explanation:
The scale factor of dilation is the ratio of the length of any of the corresponding sides of rectangle R'S'T'Q to rectangle PQRS.
R'S' = 3
RS = 15
Thus,
Scale factor = [tex] \frac{R'S'}{RS} = \frac{3}{15} [/tex]
Simplify
Scale factor = [tex] \frac{1}{5} [/tex]
