Answer: [tex]3240\ cm^2[/tex]
Step-by-step explanation:
Given: The actual length of the classroom= 18 feet
The actual width of the classroom= 20 feet
Scale factor =3 centimeters per foot
i.e. 1 foot = 3 cm
Therefore, The length of the classroom in drawing= [tex]3\times18=54\ feet[/tex]
The width of the classroom in drawing= [tex]3\times20=60\ cm[/tex]
Now, the area of the scale drawing of the classroom :-
[tex]l\times w=54\times60=3240\ cm^2[/tex]
Hence, the area of the scale drawing of the classroom =[tex]3240\ cm^2[/tex]
