Answer:
800 tiles
Step-by-step explanation:
Room :
Length of room = 6m
= 600 cm
Breadth of room = 4m
= 400 cm
Area of the room = 600 × 400
= 2400 sq.cm
Tiles :
Length of tile = 20cm
Breadth of tile = 15cm
Area of tile = 20 × 15
= 300 sq.cm
∴ No. of tiles needed to cover the floor = 2400 ÷ 300
= 800 tiles
