The total length of a football field, including end zones, is how many yards?

A football field's standard dimensions are 100 yards in length for the playing field itself, plus two end zones, each measuring 10 yards deep. This adds a total of 20 yards to the field's length, bringing the overall total to 120 yards.

Understanding the configuration of a football field is crucial, as it includes both the playing area and the end zones that are integral to scoring plays in the game. Each of these end zones is critical for touchdown completions, hence they are included in the total field length calculation. Thus, the correct total length of a football field, including end zones, is indeed 120 yards.
