Area of room = 680*320 = 217600sq.cm
Area of 1 square tile = (40)^2 = 1600sq.cm
Therefore, no. of tiles required
= Area of room / Area of 1 square tile
= 217600/1600
= 136 tiles
Area of 1 square tile = (40)^2 = 1600sq.cm
Therefore, no. of tiles required
= Area of room / Area of 1 square tile
= 217600/1600
= 136 tiles
