What is the answer ?????????????????????
Alja [10]

Answer:

Step-by-step explanation:

First off you need to identify the relationship between the 2 widths. The answer to that is 3 feet in real life = 15 inches in scale drawing. This means multiply by 5 and convert feet to inches. All you need to do is apply this to the height. We have 5 feet, if we multiply by 5 we get 25. Then remember it needs to be inches, so the answer is 25 inches.
