Question

The floor of a rectangular hall is 24 m and breadth 80 cm, will be required to cover the floor of the hall?

Answer 1

Given:
Length = 24 m
Breadth = 18 m
Thus, we have:
$$\begin{gathered} \mathrm{Area}\mathrm{of}\mathrm{the}\mathrm{rectangular}\mathrm{hall}=24\times 18 \\ =432{\mathrm{m}}^2 \end{gathered}$$

Length of each carpet = 2.5 m
Breadth of each carpet = 80 cm = 0.80 m

Area of one carpet = $2.5\times 0.8=2{\mathrm{m}}^2$

Number of carpets required = $\frac{\mathrm{Area}\mathrm{of}\mathrm{the}\mathrm{hall}}{\mathrm{Area}\mathrm{of}\mathrm{the}\mathrm{carpet}}=\frac{432}{2}=216$

Therefore, 216 carpets will be required to cover the floor of the hall.
