Final answer:
To find the actual width of the room, multiply the width on the blueprint (2 inches) by the scale factor (72) to obtain 144 inches, which is then converted to feet (12 feet) by dividing by 12.
Step-by-step explanation:
The question is asking us to determine the actual width of a room in feet when its width on a blueprint is given as 2 inches and the scale is 1 inch equals 72 inches. Since 1 inch on the blueprint corresponds to 72 inches in reality, we can calculate the actual width by multiplying the width on the blueprint by the scale factor. It's important to know that there are 12 inches in a foot.
First, we calculate the width in inches: 2 inches (blueprint) x 72 (scale factor) = 144 inches. Then, we convert inches to feet by dividing by 12: 144 inches / 12 = 12 feet. Therefore, the actual width of the room is 12 feet.
