Okay, so I know that the square root of 324 is 18, but then what?
18 * 12 = 216, so 216 ft area?

Me either. I appreciated the link you sent me, but I know area and perimeter. This is just confusing me for some reason. :/

I found this, but I think it's wrong and I don't understand their explanation.

"Since 1 foot = 12 inches, you can fit 12 tiles side by side along the 18-feet-long wall and 8 tiles along the 12-foot wall. So you need 

12 * 8 = 96 

tiles to cover the floor."
