Final answer:
The length of a football field is best measured in meters (C), as it is a large but not exceedingly long distance. An American football field is 100 yards long, and converting that to meters using the conversion of 1 yard to 0.9144 meters yields approximately 91.44 meters.
Step-by-step explanation:
- The metric unit that would be used to measure the length of a football field is the meter.
- The American football field is typically 100 yards long, excluding the end zones.
- Yards and meters are units that measure similar lengths, with a yard being slightly shorter than a meter.
- Since a football field is a sizable length but less than a kilometer, the meter is the most appropriate unit of measure.
- The conversion from yards to meters is important to know: 1 yard is approximately 0.9144 meters.
- Therefore, to convert the length of an American football field into meters, we would calculate 100 yards multiplied by 0.9144 to get approximately 91.44 meters.
