It depends on the dimensions of the tiles and their orientation.
The distance around the wall is 42 linear feet.
We ,know that :no. of tiles = area of room /area of tiles .so,no.of tiles =36 X42 /2x2=378
To determine how many 18x18 inch tiles are needed for a 42 square foot bathroom, first convert the tile size to square feet. An 18x18 inch tile is 1.5 feet by 1.5 feet, which equals 2.25 square feet per tile. Then, divide the total bathroom area (42 square feet) by the area of one tile (2.25 square feet): 42 ÷ 2.25 = 18.67. Since you can't use a fraction of a tile, you would need 19 tiles to cover the bathroom.
The answer will depend on the shape of the 168 square feet. The best that you can do, leaving no room for grout, is 42 tiles. However, if the area is circular, you will require more.
there are 102 x 42 and it would equal 4284 tiles.
42 square feet
126 feet.42 yards is 126 feet.
42 feet = 12.8016 meters
42 inches = 3.5 feet.
42 feet = 504 inches
42 feet
40*42=1680 sq. ft.
