The floor of a rectangular Hall is of length 9m and 4m. How many tiles of 20cm by 30cm can be used to cover the floor completely

Answer 1

First, we need to convert the measurements to the same units. We convert everything to cm:

Length of hall: 9m x 100 = 900cm
Width of hall: 4m x 100 = 400cm
Area of hall: 900cm x 400cm = 360,000cm²

Each tile measures 20cm x 30cm, which is an area of 20cm x 30cm = 600cm².

To find the number of tiles needed to cover the floor completely, we need to divide the total area of the hall by the area of one tile:

Number of tiles = Total area of hall/Area of one tile
Number of tiles = 360,000cm²/600cm²
Number of tiles = 600

Therefore, 600 tiles of 20cm by 30cm can be used to cover the floor completely.

Answer 2

the floor is 30x20 tiles = 600 tiles
