Calculate the area, perimeter of Polygon (Polygon Calculator) According to Wikipedia: ”In geometry, a simple polygon is defined as a flat shape consisting of straight, non-intersecting line segments or “sides” that are joined pair-wise to form a closed path. It is simple when the edges don't intersect, so if the polygon isn't crossed.Here the edge lengths as well as the perimeter and area of the polygon can be … Additionally, for polygons up to 12 sides, the polygon name will appear in the tool. You can use this given Apothem of a regular polygon calculator to calculate the apothem of a regular polygon based on given values of the side length, circumradius and number of sides for a selected type of polygon. In our perimeter calculator we've also implemented a simple formula for regular polygon perimeter: Polygon Perimeter = n * a. where n is the number of polygon sides. As the polygon is a pentagon having five sides, where each side (s) measures 12 cm, its perimeter (p) is = (5 x s) = (5 x 12) = 60 cm Now, as we know, Limitations This method will produce the wrong answer for self-intersecting polygons, where one side crosses over another, as shown on the right. The irregular polygons does not contain apothem or center. From Triangles do NOT need to be right triangles.
