Question

A rectangular building lot has a width of $75ft$ and a length of $125ft$. Determine the area of this lot in square meters.

Answer 1

Find area of rectangle building lot:

$1ft=12inches$

$$\begin{gathered} 1inch=2.5cm \\ \Rightarrow 12inches=30cm \end{gathered}$$

Then,

$$\begin{gathered} 1\mathrm{cm}=0.01\mathrm{m} \\ \Rightarrow 30\mathrm{cm}=0.3\mathrm{m} \end{gathered}$$

Therefore,

$\begin{array}{rcl}\mathrm{Area}\mathrm{of}\mathrm{rectangle}& =& \mathrm{l}\times w\\ & =& 125(0.3\mathrm{m})\times 75(0.3\mathrm{m})\\ & =& 843.75{\mathrm{m}}^2\end{array}$

Hence, the area of the building lot in meter squares is $843.75{\mathrm{m}}^2$.
