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}/100=0.2\text{ m} \\ width=17\text{ cm}/100=0.17\text{ m} \end{gathered}`

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

`area=length* width`

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

`\begin{gathered} area=0.2*0.17 \\ area=0.034 \end{gathered}`

The area is 0.034 m².
