Question

Find the cost of flooring a square room of side $600cm$ at $₹300persq.m.$

Answer 1

The side of the square $=600cm=6m$

Area of the square $=side\times side$

$$\begin{gathered} =6\times 6 \\ =36 \end{gathered}$$ \

So, the area of the square is $36m^2$.

The rate of flooring a square room is $₹300persq.m.$

So, the cost of flooring a square room $=Rate\times Area$

$$\begin{gathered} =300\times 36 \\ =10800 \end{gathered}$$

Hence, the total cost of flooring a square room is $₹10800$.
