Question

A banquet hall with a floor $25m$ long and $10m$ wide has to be covered with square-shaped shahabad stones, on each of side $50cm.$ Calculate the number of stones that will be required to cover the entire floor of the banquet hall.

Answer 1

The length of floor $=25m$

The breadth of floor $=10m$

Area of the rectangular stone $=l\times b$

$$\begin{gathered} =25\times 10 \\ =250 \end{gathered}$$

So, the area of the Rectangle is $250m^2=250\times 10000=2500000c{m}^2$.

Then we need to find the area of stones

Area of Stone $=Side\times Side$

$$\begin{gathered} =50\times 50 \\ =2500 \end{gathered}$$

Then the number of stone $=\frac{AreaofFloor}{AreaofStone}$

$$\begin{gathered} =\frac{2500000}{2500} \\ =1000 \end{gathered}$$

Hence, the number of stones is $1000$.
