A 12x24 tile is 2 square feet. There are 120 tiles that would be needed.
240 sq ft = 240x12x12 = 34560 sq inches Each tikle is 18 x 18 = 324 sq inches Thus you need 34560/324 = 107 tiles
240
12X20 = 240 sq feet 12"x12" tiles are 1 sq foot each so must be 240/1= 240
It is assumed that the question refers to a square that is 50 cm * 50 cm. And likewise with the area to be tiled (otherwise the question becomes trivial). 50 cm *50 cm = 0.5m*0.5m = 0.25 m2 240 m * 240 m = 57600 m2 So the number of tiles needed = 57600/0.25 = 230400 tiles. That is the mathematical answer and assumes that there are no breakages or other wastage.
240 square tiles are needed
A 12x24 tile is 2 square feet. There are 120 tiles that would be needed.
If you mean 20 in x 20 in tiles, the 240 sq ft room is 240 x 144 sq in = 34560 sq in. each tile is 20 x20 = 400 sq in tiles needed are 34560/400 = 86.4 tiles, say 90 tiles
(100*144)/(12*5) = 240 tiles are needed
240 sq ft = 240x12x12 = 34560 sq inches Each tikle is 18 x 18 = 324 sq inches Thus you need 34560/324 = 107 tiles
240
12X20 = 240 sq feet 12"x12" tiles are 1 sq foot each so must be 240/1= 240

1 tile = 1.77 of a square foot, 240 Sq.Ft. divided by 1.77 = 135.5 tiles ok

first put both in terms of the same mesurment. tiles in inches, patio in inches. patio is 240 by 360 inches. how many tiles will fit in the 240 inch measurement? 15 how many tiles will fit in the 360 inch measurement? 22.2 so you call it 23. 23X15=345 tiles you will need in a 20x30 area.
