Just can't seem to figure it out... silly I know.
Thanks for the help.

Assume tiles are 1.5 ft x 1.5 ft
length = 20 ft
20 / 1.5 = 40 / 3 = 13 1/3
So will require 14 tiles along length
breadth = 13 ft
13 / 1.5 = 26 / 3 = 8 2/3
So wil require 9 tiles along breadth
Total 14 x 9 = 126 tiles

Are the tiles 18" x 18" ? And will there be any space between them? Are you going to use a regular square pattern?
You need 13 and 1/3 across the 20' length: call it 14.
You need 8 and 2/3 across the 13' length: call it 9
So the whole pattern is 14 tiles x 9 tiles = 126
BUT ... if you can use the edge tiles cut 1/3 and 2/3, then you need only 14 x 8 = 112. If you do this, you will need to turn one of each of the cut pieces by 90 degrees.
Plus, add an extra 7 or 8 tiles in case of mistakes.

First, you need to convert everything into feet. 18" is 1.5 feet. Then you need to figure out how many tiles go in each direction.
x = (20/1.5)(13/1.5)
x = 13.33 * 6.66
x = 115.5555...

(20[12] * 13[12]) / 18
(240 * 156) / 18
37,440 / 18
2,080
Answer: 2,080 tiles are needed.

126... that's if you don't use one piece twice (like cut on in half for the last row)
