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 area required to cover a floor of area 1080 m2?
(If required you can split the tiles in whatever way want to fill up the corners.)

Solution

Area of a parallelograms = Base x Corresponding height
                     Area of a tile =space space space space open parentheses 24 over 100 cross times 10 over 100 close parentheses straight m squared space equals space 240 over 10000 straight m squared space equals space 0.024 space straight m squared
∴         Area of the floor  = 1080 m2
         Now, number of tiles = fraction numerator Total space area over denominator Area space of space one space tiles end fraction
                                          = fraction numerator 1080 over denominator 0.024 end fraction
                                          = 45000 tiles
