Answer: \(3240\ cm^2\)

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= \(3\times18=54\ feet\)

The width of the classroom in drawing= \(3\times20=60\ cm\)

Now, the  area of the scale drawing of the classroom :-

\(l\times w=54\times60=3240\ cm^2\)

Hence, the area of the scale drawing of the classroom =\(3240\ cm^2\)
