Question

What is the cost of tiling a rectangular plot of land $500$ m long and $200$m wide at the rate of rupee $8$ per hundred sq m.?

Answer 1

Step 1 Area of the rectangle.

Rectangle Length is $500m$

Rectangle Breadth is $200m$

Calculate the area of the rectangle:

$$\begin{gathered} \mathrm{Area}\mathrm{of}\mathrm{rectangle}=\mathrm{length}\times \mathrm{width} \\ =500\times 200 \\ =1,00,000{\mathrm{m}}^2 \end{gathered}$$

Step 2. The cost of tiling a rectangular plot.

Calculate cost of tilling plot:

$$\begin{gathered} \mathrm{Cost}\mathrm{of}\mathrm{tilling}\mathrm{per}100\mathrm{sq}.\mathrm{m}=\mathrm{Rs}.8 \\ \mathrm{Cost}\mathrm{of}\mathrm{tilling}1,00,000{\mathrm{m}}^2=\frac{(8\times 1,00,000)}{100} \\ =\mathrm{Rs}.8000 \end{gathered}$$

Hence, the cost of tiling the rectangular plot is $\mathrm{Rs}.8000$
