Use the drawing below to answer the questions that follow.

It appears that there is a drawing that is referenced in your question, but unfortunately, I cannot see images or drawings. However, I can help guide you on how to calculate the scale factor and find the missing side length if you describe the dimensions of the larger and smaller rectangles.

Part A: Scale Factor

To find the scale factor from the larger rectangle to the smaller rectangle, use the following formula:

\[ \text{Scale Factor} = \frac{\text{Dimension of Smaller Rectangle}}{\text{Dimension of Larger Rectangle}} \]

If you provide the lengths of the corresponding sides of both rectangles, I can help you calculate the scale factor.

Part B: Finding the Missing Side

If you have one dimension of the smaller rectangle and the corresponding dimension of the larger rectangle, you can determine the missing side using the scale factor:

\[ \text{Missing Side} = \text{Known Side} \times \text{Scale Factor} \]

Let me know the specific dimensions involved, and I'll help you solve these parts!
