Adollhuse has a bed with diemesions 1/12 size of a queen size bed has an area of 4,800 square inches, and a length of 80 inches. what are the side lengths of the dollhouse bed?

First we,Find the other side of the bed!

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!
