Question

A rectangle field is 0.45 kilometers long and 0.3 kilometers wide. What is the area of the field in square meters? Do not round your answer. Be sure to include the correct unit in your answer.

Answer 1

`135,000\text{ }m^2`

Step-by-step explanation

We want to find the area of the rectangular field.

The area of a rectangle is given by:

`A=L*W`

where L = length

W = width

To find the area of the field in square meters, we first have to convert its length and width from kilometers to meters as follows:

`\begin{gathered} 1km=1000m \\ \\ 0.45km=0.45*1000=450m \\ \\ 0.3km=0.3*1000=300m \end{gathered}`

Therefore, the area of the rectangular field is:

`\begin{gathered} A=450*300 \\ \\ A=135,000\text{ }m^2 \end{gathered}`

That is the answer.
