regular (left) and irregular (right) polygons pol·y·gon (pŏl′ē-gŏn′) n. A closed plane figure bounded by three or more line segments. [Late Latinpolygōnum, from Greekpolugōnon, from neuter of Greekpolugōnos,polygonal:polu-,poly-+-gōnos,angled; see-gon.] ...
Area of n-sided polygon. In summary, whenever we can break an irregular polygon into different regular polygons, we only need to know how to calculate the area of regular polygons and add them up. The following sections will show how to partition a polygon and introduce the coordinate syste...
*4.5(Geometry: area of a regular polygon) A regular polygon is an n-sided polygon in which all sides are of the same length and all angles have the same degree (i.e., the polygon is both equilateral and equiangular). The formula for computing the area of a regular polygon is Here, ...

Area of a Pentagon is the region enclosed by its five sides. A pentagon can be divided into five equal isosceles triangles to find the area of pentagon formula. Find area using apothem and sides of pentagon.
How do you find the area of a 5-sided polygon? If the apothem isn't known, it should be solved first using the apothem formula. Then the regular polygon formula can be applied. Multiply the side length and the apothem. Then multiply this number by 5/2 - 5 for the number of ...
Type the number of sides, along with a known property, and the polygon area will appear in no time. If you're wondering how to find the area of a polygon or what is the area of a polygon formula, keep reading. If you want to calculate the area of any 3-sided or 4-sided polygon...
I just thought I would share with you a clever technique I once used to find the area of general polygons.The polygon could be regular (all angles are equal and all sides are equal) or irregularRegular IrregularThe Example PolygonLet's use this polygon as an example:...
PolygonA = (a2× n) ÷ (4 × tan(π÷ n)) Irregular QuadrilateralA = 1/2 × d × (h1+ h2) How to Find Area of a Square A square is a polygon (two-dimensional shape) with four equal straight sides and four equal interior right angles. ...
