Question

A model of a skyscraper was made by an architect. The model was 10 inches high. If the architect used a scale of 2 inches represents 12 feet, What would be the actual height of the building?A: 12ftB: 240ftC: 120ftD: 60ft

Answer 1

The scale is 12ft:2in, then the actual height of the building is

`\begin{gathered} (12ft)/(2in)=(x)/(10in) \\ x=(10in*12ft)/(2in) \\ x=60ft \end{gathered}`

The actual size of the building is D: 60ft.
