The scale factor is

Answer 1

To determine the scale factor, you can compare the dimensions of the original rectangle to the dimensions of the scaled copy.

Given:
- In the original rectangle, one side corresponds to 1 unit.
- In the scaled copy, the same side corresponds to 2 units.

The scale factor can be calculated using the formula:

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

Plugging in the values:

\[
\text{Scale Factor} = \frac{2 \text{ units (scaled copy)}}{1 \text{ unit (original rectangle)}} = 2
\]

Therefore, the scale factor is \( \text{2} \).
