Apply the 1:4 scale to both the width and length of the 12x24 paper If you have 4 inches for every 1 inches, you are multiplying each dimension by a factor of 4

idk, read it and tell me what you don't get. basically for every 1 inch, you have 4 inches, so we multiply both sides by 4 and see whether or not it matches the 48x120 thing
OpenStudy (bibby):
other way around. so we have |dw:1393028537523:dw| the right shape is what we have after applying the scale, the left is what we want
OpenStudy (bibby):
It's not reasonable, can you not see why?

Exactly. The dimensions aren't both equal (well the length mainly)
