Find the number of square tiles of side 5 cm required to cover the floor of a room of length 6 m and breadth 3 m
Answers
The number of tiles required to cover the floor of the room is 7200.
Explanation:
For each square tile,
The length of each side is 5 cm.
∴ Area of each tile = (side)²
= (side × side)
= (5×5) cm²
= 25 cm².
∴ The area of each tile is 25 cm².
For the floor,
Length = 6 m
= (6× 100) cm [∵ 1 m = 100 cm.]
= 600 cm
Breadth = 3 m
= (3×100) cm [∵ 1 m = 100 cm.]
= 300 cm
∴ Area of the floor = (Length× Breadth)
= (600×300) cm²
= 180000 cm²
∴ The area of the floor is 180000 cm².
∴ The number of tiles required to cover the floor of the room _
(The area of the floor ÷ The area of each tile)
=(180000÷25) tiles
= 7200 tiles.
∴ 7200 tiles are required to cover the floor of the room with tiles.
