Answer:

22 ft^2

Explanation:

A scale drawing for a home construction project uses a scale factor of 3.

Given The area of the actual rectangular family room is 198 ft^2.

Now area of the rectangle is length* width= l*w

the scaling factor must have multiplied with both length and width

Area = 3l*3w= 192

⇒l*w= 198/9= 22 ft^2

The area of the scale drawing of the rectangular family room= 22 ft^2
