Which would be 60 since 4800/80(the other side) would give us 60
now we take 80 and divide it by 12 ( since the dimension is 1/12) to get 6.667
now we do the same for the 60 ( the other side that we found above) so 60/12 would equal 5
So now we multiply the two new found numbers (5 and 6.6667) 5 * 6 = 30
So your answer would be 30 Inches squared.... I hope that this helps you!! I got 20 by 20 equals 400 inches squared so the sides would be 20 message me for more!
Divid to get the other side :) so if the doll house is 1/12 of the queen size bed you divid each side by 12 see. 4800/80=60. 80/12=6.6667.... so 60/12=5. so then 5x6 1/3. hope this helps you ... goood luck! :)
