Question

Which scale factor did Jorge most likely us to dilate figure ABCD to get A'B'C'D

Answer 1

The side length of square ABCD is 3 units

The side length of square A'B'C'D' is 1 unit

The scale factor is by what number we multiply the side length of ABCD to get A'B'C'D'.

Let that be "x", so we can say >>>

3 times "what number" to get 1

or,

3 times x to get 1

In equation, that is:

$3x=1$

Solving for x:

$\begin{gathered} 3x=1 \\ x=\frac{1}{3} \end{gathered}$

Hence,

The scale factor is

$\frac{1}{3}$
