Answer:
The field has an area of 0.135 km².
Explanation:
We first convert the measurements from meters to kilometers by dividing by 1000.
- - - - - - - - - - - Length: 450 m = (450/1000) km = 0.45 km
- - - - - - - - - - - Width: 300 m = (300/1000) km = 0.3 km
So the field is a rectangle 0.45 kilometers long and 0.3 kilometers width.
To compute the area of this rectangle, we multiply its length by it's width.
- - - - - - - - - - - Area = 0.45 × 0.3 = 0.135 km².
So the answer is 0.135 km².
