Question

The area of a room is 15 sq meter How many tiles of length 50cm and breadth 30cm will be needed to cover the floor?

Answer 1

Answer:

100 tiles are needed to cover the floor.

Step-by-step explanation:

Area of room in square meters = 15 Square metre

1 Square metre = 10,000 centimetres

Hence the area of the room = 15 × 10,000 centimetres

H

Area of the room = 1,50,000 centimetres²

Hence the area of room is 1,50,000 cm square

Area of tiles = length × breadth

Length of the tile = 50 centimetres

Breadth of the tile = 30 centimetres

Area of the tile = 50cm × 30cm

Area of the tile = 1500 centimetres²

Number of tiles needed to cover the floor = Area of the room / area of the the tile

Number of tiles needed to cover the floor = 1,50,000 / 1,500

Number of tiles needed to cover the floor  =100  tiles

100 tiles are needed to cover the floor.
