Answer: the scale factor used in Edna's drawing is 1.5. It means that every inch on the drawing represents 1.5 feet in real life.
Step-by-step explanation: So, in Edna's drawing, she used a scale of 6 inches = 4 feet. To find the scale factor, we need to compare the measurement on the drawing to the actual measurement. In this case, we'll compare inches to feet.
Step 1: Take the measurement on the drawing (in inches) and divide it by the corresponding measurement in real life (in feet).
6 inches ÷ 4 feet = 1.5
Step 2: The result of the division is the scale factor. So, the scale factor for Edna's drawing is 1.5.
Hope that helps.
