Answer:
9/12
Step-by-step explanation:
You have to divide 36 by 4 to get 9 and then divide 48 by 4 and you will get 12.
As there are 81 tiles total, that makes your area 81. Being a square, that makes your area equation A=s^2. As you need a side, this makes your equation s=√A. Plugging in 81 as A, we get s=√81=9, so an edge has 9 tiles.
