Question

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 $1080$ sq. metre.

Answer 1

Area of one tile $=24\times 10=240$ cm${}^2$

It is known that $1$ sq. meter $=10000$ $c{m}^2$

Required no. of tiles $=\frac{\text{Total Area}}{\text{Area of one tile}}=\frac{1080\times 10000}{240}=45000$ tiles
