basketball court
object of the game is to shoot the ball through the hoop at either end of the court. When the game was first invented, actual baskets were used. Dr. James Naismith's original rules specified that "A goal shall be made when the ball is thrown or batted from the grounds into the basket and stays there, providing those defending the goal do no touch or disturb the goal. However, because it proved to be inconvenient to continually retrieve the ball from the baskets, the baskets were soon replaced by metal hoops (usually with dangling netting attached to direct the ball straight down.) In the N.B.A., the court is 94 feet by 50 ft (28.65 m by 15.24 m). Under International Basketball Federation (FIBA) rules[2], the court is slightly smaller, measuring exactly 28 m by 15 m (91'10.4" by 49'2.6"), although national federations are allowed to use smaller courts, as long as they are at least 26 m by 14 m (85'3.6" by 45'11.2"). A high school court is slightly smaller, at 84' by 50' and some elementary schools have courts measuring 74' x 42'.
