Final answer:
The length of an American football field is 100 yards, which is approximately 91.4 meters when converted from yards to meters using the standard measurement that 1 yard is equivalent to 3 feet and 1 meter equals 3.281 feet.
Step-by-step explanation:
To calculate the length of an American football field in meters, we use the standard measurement that 1 yard is equivalent to 3 feet. Since there are 3.281 feet in a meter, we can convert the field's length from yards to meters.
The length of an American football field is 100 yards, excluding the end zones. First, we convert the length to feet:
100 yards x 3 feet/yard = 300 feet
Next, we convert feet to meters:
300 feet / 3.281 feet/meter ≈ 91.4 meters
Therefore, the length of an American football field is approximately 91.4 meters.
