Answer:
192
Step-by-step explanation:
First you need to figure out how many inches long the top and side are:
8*12 = 96
2.5*12 = 30
Then you figure out how many tiles you can fit on one side. so what I did was divided 96 by 6 because they are both the long sides and I need to know how many of the tiles can fit on the long side.
96/6 = 16
30/2.5 = 12
Know you know that 16 tiles can fit the long ways and 12 can fit the short way so then you multiply them because you want to know how much can cover an area.
16*12 = 192
there you go hope this helped. its a little confusing or if you have questions just ask :)
