To determine the scale factor that Camila uses, we need to compare the original dimensions of the telegram (on the left) with the new dimensions of the telegram (on the right).
If both the original and the new telegram are 9 inches (assuming this means all dimensions of the telegram measure 9 inches), the scale factor can be calculated using the formula:
\[ \text{Scale Factor} = \frac{\text{New Size}}{\text{Original Size}} \]
If both sizes are the same (9 inches), then:
\[ \text{Scale Factor} = \frac{9}{9} = 1 \]
This indicates that Camila is not resizing the telegram at all; she is using a scale factor of 1. If there is more specific information regarding the dimensions or a different measure for either the original or the new telegram, please provide that, and I can help you further calculate the scale factor.
