25. you will have an excess though because 16 doesnt go into 77 evenly. so you have to go to the lowest number of tiles that is greater than 77 which is 80. that means for every outer tile (there are 16) you have an excess sq ft of tile of 3/16 which is .1875. and since .1875 x 16 = 3, you have an excess of 3. :)

If the area is "well behaved" or if most offcuts are used then 77 tiles will suffice. However, if the area is not rectangular then you are likely to require more. Also, unless the length or width of the rectangular area is an exact multiple of 19.5 inches, there will be many off-cuts.
