From the Latin arĕa, the concept of area refers to a land space that falls within certain limits. In this sense, an area is a space delimited by certain geographic, zoological, economic or other characteristics.
Area is also used as a synonym for terrain, in the sense of being a field of action or an order of ideas. For example: “I cannot answer that question since it corresponds to the area of physical science and I am a sociologist. ”
An area is also a unit of surface equivalent to 100 square meters. It is known as a square decameter, although the use of its multiple called hectare (10,000 square meters) is more frequent.
In the same way, there are many other types of areas that become part of our day to day. Thus, for example, we find the so-called rest areas that are those spaces that are enabled next to the roads, specifically highways and expressways, so that the drivers who are driving through them can stop and rest.
There are also the so-called service areas, which are those that are annexed to the mentioned types of roads and whose clear objective is that the driver on the move can stop to cover any need. And it is that in these areas there are both gas stations, where they can refuel, as well as shops and hospitality establishments where they will have the opportunity to eat, have a coffee or buy any product they need for the rest of the journey.
And all this without forgetting the existence of what is known as a metropolitan area. This last one is an extension of land that is conformed by a central city, which is the one that gives the name to that one, and by various satellite cities that are around it.
An example of this last type of area exists in Spain and specifically in the community of Madrid. Thus, we find the metropolitan area of Madrid that is made up of the city that gives it its name and other nearby towns such as Alcalá de Henares, San Sebastián de los Reyes, Villaviciosa de Odón, San Fernando de Henares, Tres Cantos or Torrejón de Ardoz.
For geometry, an area is the surface within a perimeter, which is expressed in units of measurement that are known as surface. There are different formulas to calculate the area of the different figures, such as triangles, quadrilaterals, circles, and ellipses.
Finally, we can mention that, in some games and sports, the area is an area located just in front of the goal. This area is one of the most important in the dynamics of the game and they usually contemplate special punishments for the fouls that are committed in it. In soccer, for example, if a player commits a foul within the area defended by his team, the referee sanctions a penalty free kick, which is a shot that is taken without a barrier (i.e., without players standing between the kicker and the goalkeeper) from a point eleven meters from the goal line.
