Answer:
2 Sandwiches
Step-by-step explanation:
So this is a proportion. The scale is 9 inches tall and the real is 30 feet. First, multiply feet by twelve to find inches.
So the real item is 360 inches tall. So the proportion is 9:360. Or 1:40. The scale is 1/40 the size of the real item. Or the real item is 40 times the size of the scale.
So if the scale drawing is 21 inches long, that means the real item is 40 times longer, or 40·21
Therefore the real item is 840 inches long. Divide it by twelve to find how many feet long it is.
840/12=70
Therefore the real item is 70 feet long.
