Question

How many tiles are required for a room of length 4 m and 3 m, if the length of each tile is 4 cm and breadth 3 cm?

Answer 1

Dimensions if the room = 4m × 3m = 4 ×100cm ×3 × 100cm.

Dimensions of the tile = 4 cm × 3 cm.

Therefore no. of tiles required = Dimensions of floor/Dimensions of the tile = 400cm × 300cm/4cm×3cm= 10,000

Answer 2

Answer:

Step-by-step explanation:

Ar. of room= 4*3

                 =12 m(square) OR 12 * 100* 100 = 120000cm(square)

ar. of tile = 4*3

              =12 cm(square)

therefore no. of tile = area of room area of each tile /

                                =120000/12

                                 =10,000 tile
