    666.67 ft^2

    Step-by-step explanation:

    We start with a 4x5 scale room

    We then use the 1:20 scale to multiply the 4 and the 5 by 20

    4*20=80

    5*20=100

    We now have the dimensions of the actual room, 80in. x100in.

    Area=length*width

    A=100*80

    A=8000 in^2

    We are not done yet, though. To get feet, you convert inches to feet. 1 foot=12 inches.

    8000/12=666.667, or 666.67, or 667, depending what you would round to
