Similarly, different shape requires a specific formula. To find the area of a regular polygon, you use an apothem — a segment that joins the polygon’s center to the midpoint of any side and that is perpendicular to that side (segment HM in the following figure is an apothem). Regular Nonagon Then, divide the total by 2 to get the area. It is always a two-dimensional plane. https://www.mathopenref.com/polygonregulararea.html, https://www.mathsisfun.com/definitions/apothem.html, https://www.mathopenref.com/coordpolygonarea.html, De oppervlakte van een veelhoek berekenen, consider supporting our work with a contribution to wikiHow, Perimeter = the sum of the lengths of all the sides, Apothem = a segment that joins the polygon's center to the midpoint of any side that is perpendicular to that side. If it is 3 sided or 4 sided – a triangle and a square – then we know the formula for area, but I was thinking – what about a formula that works for any regular polygon – That is to say, one with all the sides the same. =. {\displaystyle A={\tfrac {1}{2}}\cdot p\cdot r.} How do I calculate the area of an octagon? a = length of a side . Limitations This method will produce the wrong answer for self-intersecting polygons, where one side crosses over another, as shown on the right. This article has been viewed 1,246,071 times. A regular polygon is equilateral (it has equal sides) and equiangular (it has equal angles). Using these formulas, the area of any polygon can be found by dividing the polygon into triangles. copy the formula in cell next to the bottom for a five row or the same as the number of in this example, how to measure the area of the polygon, divide the area of the polygon by the number of sides the polygon has. Assume we have a polygon represented with the set of points. The area is simple [(6 + 8) x 10]/2, which can be simplified to (14 x 10)/2, or 140/2, which makes for an area of 70. The Algorithm – Area of Polygon The idea here is to divide the entire polygon into triangles. For shapes with curved boundary, calculus is usually required to compute the area. Perimeter of Polygon(P) = n x s. Area of polygon formula of a regular n-sided polygon with s as the length of the sides is given by s/2tan(180/n) Area of Polygon(A) = s/ 2 tan (180/n) Solved Examples. You can think of it this way because the hexagon is made up of six equilateral triangles. How do I calculate the area of a quadrilateral polygon? The area of a circle is equal to $\pi$ per radius ($r$) squared: With what you learned and a little common sense you can now calculate the area of a circular sector and the area of a circular segment. Formulas to Calculate. By using our site, you agree to our. If the square has a side length of 6, then the area is 6 x 6, or 36. How to Find the Area of Polygon? Calculate the Area of a regular polygon if given side and number of sides Formula for area of regular polygon - Calculator Online Home List of all formulas of the site For the calculation of the area of the triangle, we will use the famous base formula for height over two: And we are going to see 3 ways in which triangles can be presented to us when applying the aforementioned formula because sometimes the brain deceives us. To calculate the area of a regular polygon, use the specific formula for that shape. Remember that: b = base . Each Area calculator is shown below. The bottom side of the triangle is 20 units long. a=1/2ap. Include your email address to get a message when this question is answered. There are several well-known formulas for the areas of simple shapes such as triangles, rectangles, and circles. for example, if the area of a square is 36, math open reference: regular polygon area formula;. Calculating the perimeter and area of a polygon is an often-discussed topic in geometry and is the essence and soul of geometry, with the exception of circles or curved lines.
