Question

Henry painted a picture of his house on canvas. The actual width of

the driveway is 20 feet. If it is represented with a width of 4 inches on
the canvas, what was the scale factor used?

Answer 1

The scale factor would be -5.

Explanation:

If the driveway is 20 feet but 4 foot on the canvas. Then 20/4 is 5. But since the width is going from 20 to 4, the numbers are going down to it would be a negative scale factor. If it was going from 4 width to 20 width, the scale factor would be a positive 5.
