Answer:
We know that:
1 inch in the drawing, equals 3 feet in the real room.
Then if the scale is 6 in by 4 in, the actual room is:
6*3ft by 4*3ft
18ft by 12ft.
The total area of the room is:
18ft*12ft = 216ft^2.
Now we know that the price of the carpet is $5,50 per square ft,
The area of the room is 216 ft^2, then if we want to carpet the whole room, we need to pay 216 times $5.50.
Cost = 216*$5.50 = $1,188
