A flooring tile has the shape of a parallelogram whose base is 24 cm and the corresponding height is 10 cm. How many such tiles are required to cover a floor of area 1080 m2? [If required you can split the tiles in whatever way you want to fill up the corners]

Given: Base of flooring tile = 24 cm = 0.24 m
Corresponding height of a flooring tile = 10 cm = 0.10 m
Now Area of flooring tile = Base x Altitude = 0.24 x 0.10 = 0.024 m²
∴ Number of tiles required to cover the floor = Area of floor/Area of one tile
= 1080/0.024
45000 tiles
Hence 45000 tiles are required to cover the floor.
