Contour of a surface or figure and the measure of its contour
The term perimeter refers to the contour of a surface or figure and also to the extent that said contour is observed..
Sum of all its sides
In more informal terms, the perimeter, in any figure, will be the sum of all sides of this. From what has been said, then, it follows that the perimeter will allow calculating the boundary of a surface, a fact that is usually very useful in various settings and contexts.
Because for example, if someone's particular need is to provide greater protection to their home or field, knowing the perimeter of that field or house will make it much simpler and easier for us to calculate how much material we need to build. a wire around them and fence them in order to obtain the security that is desired.
Calculation of the perimeter
Then, to calculate any perimeter it will be a condition without equanom know the length of all sides. The perimeter of a square in which each of its sides measures 4 centimeters will be 16 centimeters, that is, the square has four visible sides, the calculation is very easy: 4 + 4 + 4 + 4 = 16.
On the other hand, it is also important to know the value of a perimeter in question because, in some situations, it can help us to know some unknown data, such as the length of one of its sides. In this case, the calculation is also very simple, having to apply the well-known simple rule of three.
Example, if we know that the perimeter of a triangle is 16 centimeters and that the length of two of its sides is, 4 and 3, the third in question will measure 9 centimeters.
Military: a relevant area in defense and security matters
On the other hand, in the military field, the concept is widely used since it designates a relevant area in terms of defense and security, or failing that, an area that turns out to be highly valued because there are an extremely important facility for the militia.
For example, these areas have rigorous military custody and it will certainly be difficult to outflank it and cross it if you do not have the proper authorization to do so.
Generally there are soldiers covering the entire perimeter of that area and if an intruder approaches, they will be intercepted to find out what he is doing there.
Legal: restriction that an individual has to approach a place or person
In another area where the word also has a recurring use, it is at the judicial level since it is common for this terminology to be used when you want to indicate a restriction that an individual has to approach a place or a particular individual who resides in a determined direction.
Normally it is said that such a person has received from the judge a restraining order to approach another and therefore will not be able to cross a certain perimeter that the law has set for him. If he does, a punishment will fall on him and of course he will be punishable by such action.
Cases of domestic violence, where for example one of the spouses exercises direct violence against the other, and also against their children, often trigger these types of requests for perimeter restriction to approach them. The lawyer who defends the victim usually requests this provision from the judge who understands the case because there is concrete evidence that his defendant may be the object of a serious attack that puts his health and life at risk.
Unfortunately, in recent times, as a consequence of the increase in cases of gender violence, these requests have multiplied.
