A rectangular field is 0.45 kilometers long and .4 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.

The area of a rectangle is given by the formula:

\[
\text{Area} = \text{length} \times \text{width}
\]

In this case, the length of the field is \( 0.45 \, \text{km} \) and the width is \( 0.4 \, \text{km} \). First, we convert both dimensions to meters since the problem asks for the area in square meters.

1 kilometer = 1,000 meters, so:
\[
0.45 \, \text{km} = 0.45 \times 1000 = 450 \, \text{m}
\]
\[
0.4 \, \text{km} = 0.4 \times 1000 = 400 \, \text{m}
\]

Now, calculate the area in square meters:
\[
\text{Area} = 450 \, \text{m} \times 400 \, \text{m} = 180,000 \, \text{m}^2
\]

Thus, the area of the field is **180,000 square meters**.
