Question

The side that corresponds to 2 units in the original rectangle is 4 units in the scaled copy.
What is the scale factor?
Original Rectangle

5
2
Scaled Copy

4
The scale factor is

Answer 1

To find the scale factor, you can use the formula:

\[
\text{Scale Factor} = \frac{\text{Length in Scaled Copy}}{\text{Length in Original Rectangle}}
\]

In this case, the side that corresponds to 2 units in the original rectangle is 4 units in the scaled copy. Thus, we can set up the calculation as follows:

\[
\text{Scale Factor} = \frac{4 \text{ units (scaled copy)}}{2 \text{ units (original rectangle)}} = \frac{4}{2} = 2
\]

The scale factor is **2**.
