Question

In the figure above, rectangle R'S'T'Q' is a dilation of rectangle RSTQ. What is the scale factor of the dilation?

Answer 1

Answer:

A. $\frac{1}{5}$

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 = $\frac{R'S'}{RS} = \frac{3}{15}$

Simplify

Scale factor = $\frac{1}{5}$
