Answer:
7.5 feet
Step-by-step explanation:
Scale of the Model =5 in: 25 ft.
If we divide both sides by 5
[tex]\dfrac{5 in.}{5} : \dfrac{25 ft.}{5}\\\\$1 inch: 5 feet[/tex]
If a window on the model is 1.5 inch wide, from the unit ratio derived above we then have that:
1 Inch X 1.5 : 5 feet X 1.5 feet
1.5 Inch : 7.5 feet
Therefore, if a window in the model is 1.5 in. wide, the actual window is 7.5 feet wide.
