Solution

The correct option is C $$45000$$
Area of the parallelogram $$=$$ Base$$\times $$Height

So area of each tiles $$=24\times 10=240 \:cm^2$$

Area of the floor $$=1080 \: m^2=(1080\times 100\times 100)  \: cm^2$$

$$\therefore$$ Required number of tiles $$=\dfrac{\text{Area of the floor}}{\text{Area of each tiles}}=\dfrac{10800000}{240}=45000$$
