Football is a sport played between two teams of eleven players each on a rectangular-shaped playing field or pitch that is marked by lines
The surface of the pitch could be either grass or artificial turf
While the two longer boundary lines are called touchlines, the shorter boundary lines are called goal lines. The playing field is divided into two halves by a halfway line
The Length (touch line) of the pitch must be a minimum of 100 metres (110 yards) and a maximum of 110 metres (120 yards)
The Width (goal line) of the pitch must be a minimum of 64 metres (70 yards) and a maximum of 75 metres (80 yards)
Note: The lines drawn shouldn’t be more than 5 inches or 12 cm
Goals
Goals, consisting of two goalposts and a horizontal crossbar, are placed in the centre of the goal lines
Cards
In general, there are two types of cards in football, and they are displayed by umpires, when players commit offences like displaying unsporting behaviour, violating laws of the game, and delaying the play, among other offences
Yellow card
It is issued to warn players for involving in misconduct for the first time during the course of the game
Red card
Considered a severe penalty in football, a red card means the dismissal of a player from the field, and no substitution is allowed further
If a player receives two yellow cards in a match, the player automatically gets a red card
