Area of floor = length * breadth=5*3=15 m^2=150000 cm^2.
Area of a square tile = 25*25=625cm^2. Tiles required =150000/625=240 tiles

240 square tiles required of side 25 cm to cover floor of room size 5m * 3m
Step-by-step explanation:
The length and breadth of a floor of a room is 5m by 3m
1m = 100 cm
Length = 5m = 500 cm
Breadth = 3 m = 300 cm
Area of Floor = Length * Breadth
= 500 * 300 cm²
Square tile of Side = 25 cm
Area of tile = 25 * 25 cm²
Number of tiles required = Floor Area / Area of Tile
=> Number of tiles required = 500 * 300 / ( 25 * 25)
= 20 * 12
= 240
240 tiles required
