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).

उत्तर
Area of parallelogram = Base × Height
Hence, area of one tile = 24 cm × 10 cm = 240 cm2
Required number of tiles = `"Area of Floor"/"Area of each tile"`
= `(1080 m^2)/(240 cm^2) = ((1080 xx 10000) cm^2)/(240 cm^2)` (∵ 1m = 100 cm)= 45000 tiles.
Thus, 45000 tiles are required to cover a floor of area 1080 m2.
