Answer 1

To figure out the answer, the given parameters have to be converted to meters.

The conversion from centimeters to meters is given to be:

$100\text{ cm}\to1\text{ m}$

Therefore, the parameters are converted by dividing by 100 as shown below:

$\begin{gathered} length=20\text{ cm}\div100=0.2\text{ m} \\ width=17\text{ cm}\div100=0.17\text{ m} \end{gathered}$

Hence, the area of a rectangle formula can be applied:

$area=length\times width$

Substituting known values, the area is calculated as shown below:

$\begin{gathered} area=0.2\times0.17 \\ area=0.034 \end{gathered}$

The area is 0.034 m².
