Final answer:
The area of a football field is measured in the SI derived unit, meters squared (m^2), which is derived from the base unit for length, the meter.
Step-by-step explanation:
The measurement of area, such as the area of a football field, is typically expressed in square units. In the International System of Units (SI), the base unit for length is meter, so the derived unit for area would be meters squared (m2). Therefore, the area of a football field is appropriately measured in meters squared (m2).
