Question

19. How many tiles of length 50cm and width 80cm are needed to file the floor

of a bed room of 200cm long and 400cm wide?

Answer 1

You will need 20 tiles of length 50cm and width 80cm to fill the floor of the bedroom

Explanation:

To find out how many tiles you need, we'll first calculate the area of one tile:

Area of one tile = Length × Width = 50 cm × 80 cm

Next, we'll calculate the area of the bedroom:

Area of the bedroom = Length × Width = 200 cm × 400 cm

Finally, we'll divide the total area of the bedroom by the area of one tile to get the number of tiles needed:

Number of tiles needed = Area of the bedroom / Area of one tile

Let's do the calculations:

Area of one tile = 50 cm × 80 cm = 4000 square centimeters

Area of the bedroom = 200 cm × 400 cm = 80000 square centimeters

Number of tiles needed = 80000 square centimeters / 4000 square centimeters per tile

Number of tiles needed = 20

You will need 20 tiles of length 50cm and width 80cm to fill the floor of the bedroom
