Question
A rectangular field is 0.4 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.
Solution
To find the area of a rectangle, you multiply the length by the width.
- Convert the dimensions from kilometers to meters. There are 1000 meters in a kilometer, so 0.4 kilometers is 400 meters and 0.3 kilometers is 300 meters.
- Multiply the length (400 meters) by the width (300 meters) to find the area.
400 meters * 300 meters = 120,000 square meters
So, the area of the field is 120,000 square meters.
