Question

A square room of side $12m$ is to the proved with square tiles of side $50cm$ then find the number of tiles required to space the floor of the room?

Answer 1

Let the number of square tiles required be $x$

so,

Area of room = Area of 'x' tiles

Area of room$=side\times side=12\times 12=144m^2=1440000c{m}^2$

Area of 1 tile$=50\times 50=2500c{m}^2$

Area of 'x' tile$=2500xc{m}^2$

Number of tiles required$=\frac{1440000}{2500}=576$

So, 576 tiles are required
