The scale factor of the drawing is 1: 72 in inches.
Step-by-step explanation:
Step 1:
If 1 inch on the drawing is equal to 6 feet of the unscaled drawing, we can determine the scale factor by dividing the measurement after scaling by the same measurement before scaling.
Here the measurement after scaling is 1 inch and the same measurement before scaling is 6 feet.
Step 2:
The units are different so we must convert them into the same units first.
If 1 feet = 12 inches, then 6 feet = 72 inches.
So the scale factor is 1: 72.
