Answer:
The area of the scale drawing is [tex]67.5\ cm^{2}[/tex]
Step-by-step explanation:
The scale drawing is
[tex](1\frac{1}{2})/2\ \frac{cm}{ft}[/tex]
Convert to an improper fraction
[tex](1\frac{1}{2})=3/2[/tex]
substitute
[tex](1\frac{1}{2})/2=(3/4)=0.75\ \frac{cm}{ft}[/tex]
The area is equal to
[tex]120\ ft^{2}[/tex]
substitute
[tex]120*(0.75)^{2}=67.5\ cm^{2}[/tex]
