A tennis court is a rectangular area where the game of tennis is played. It is divided by a net in the middle and has specific markings for singles and doubles matches. The surface can be made of various materials, such as grass, clay, or hard court, each affecting how the ball bounces and how players move. Players use a tennis racket to hit a tennis ball back and forth over the net, aiming to score points by making the ball land in the opponent's court. The game can be played in singles (one player on each side) or doubles (two players on each side), making it a fun and competitive sport for everyone.
