Final answer:
The American football field is 100 yards long, which converts to 91.44 meters using the conversion factor that 1 meter equals 3.281 feet.
Step-by-step explanation:
The length of an American football field is 100 yards (yd), excluding the end zones, and we are looking to convert this measurement into meters (m). Since 1 yard is equivalent to 3 feet, we first convert 100 yards into feet:
- 100 yd * 3 ft/yd = 300 ft
Next, we use the given conversion that 1 meter equals 3.281 feet to convert feet into meters:
- 300 ft / 3.281 ft/m = 91.44 meters
Therefore, the length of an American football field in meters is 91.44 m, which corresponds to option a) (91.44) m.
