The basic unit of area in the metric system is the square meter, which is a square that has 1 meter on each side: 1 square meter. Be careful to say "square meters" not "meters squared":A regular polygon has all angles equal and all sides equal, otherwise it is irregular : Regular : Irregular . Concave or Convex. A convex polygon has no angles pointing inwards. More precisely, no internal angle can be more than 180°. If any internal angle is greater than 180° then the polygon is concave.

Area is defined as the total space taken up by a flat (2-D) surface or shape of an object. The space enclosed by the boundary of a plane figure is called its area.

In some cases, you may want to know how many hectares of an area in a layer. If you have one polygon, this would not be a problem. But what if you have many polygons/areas in the layer? To calculate each area one by one is almost impossible. The area of a regular polygon is one-half the product of its apothem and its perimeter, i.e., Area = 1 2 × a × p, where a is the length of an apothem, and p is the perimeter. Therefore, formula for area of a regular polygon is Area = 1 2 × s 2 tan θ 2 × p. Therefore, Area = 1 2 × s 2 tan θ 2 × n × s = n s 2 4 tan θ 2.The rectangle has an area of 15.
