What is the length of a high school basketball court in feet?

The length of a high school basketball court is indeed 84 feet. This dimension is established by the NFHS (National Federation of State High School Associations) rules governing high school basketball. Courts of this length are designed to provide an appropriate area for the gameplay, allowing for adequate space for players to move, implement strategies, and execute plays effectively.

The other options represent lengths that do not conform to standard high school regulations. For example, the standard dimensions ensure that the court size meets the developmental and competitive needs of high school athletes, making 84 feet the precise answer to the question.
