Origin: [Gr. ; peri` around + measure: cf. F. primtre.]
A perimeter is a path that surrounds a two-dimensional shape. The word comes from the Greek peri and meter. The term may be used either for the path or its length - it can be thought of as the length of the outline of a shape. The perimeter of a circle or ellipse is called its circumference. Calculating the perimeter has considerable practical applications. The perimeter can be used to calculate the length of fence required to surround a yard or garden. The perimeter of a wheel describes how far it will roll in one revolution. Similarly, the amount of string wound around a spool is related to the spool's perimeter.

Currently natural parks use a lot of resources against poaching, two very clear examples are, in the first place, the hiring of helicopters to chase poachers or locate elephants or things like these. They use a big part of their budget for that. With the budget national parks spend on a three month helicopter rental, we could fill the air with drones. And use technology better. On the other side, if they need to monitor the perimeter of the whole area they use two or three-men crews. What we could achieve if we placed drones in specific parts of the park is full monitoring of the park in only a few hours or a few minutes.
