Debbie drew a scale drawing of a hotel. she used the scale 1 inch = 3 feet. if a room in the hotel is 4 inches in the drawing, how wide is the actual room?

The scale Debbie used was 1 inch = 3 feet. That means that every inch Debbie draws represents 3 feet.

Debbie drew a room that was 4 inches (wide, I'm assuming). That means you need to multiply 3 feet by 4 (for every inch that she drew):


The width of the room is 12 feet.
