Area of a regular polygon formulas The most popular, and usually the most useful formula is the one that uses the number of sides nn and the side length aa: A=n×a2×14cot(πn)A=n×a2×41cot(nπ) However, given other parameters, you can also find out the area: A=n×a×ri...
As someone pointed out in the comments, in practice you might want to subtract the minimumxvalue from all thexcoordinates and the minimumyvalue from all theycoordinates before using the formula. Why’s that? If you add a constant amount to each vertex, you move your polygon but you don’...
Work out the width (the difference between the "x" coordinates 2.66 and 0.72)2.66-0.72 = 1.94The area is width×height:1.94 × 3.495 = 6.7803Add Them All UpNow add them all up!But the trick is to add when they go forwards (positive width), and subtract when they go backwards (...
We have taken the information from the table above and put it all on one easy to use simple sheet. This sheet contains all the formula for finding the area of different regular polygons, from equilateral triangles to dodecagons. The sheet also shows the general formala for finding the area...
The properties of each of these structures can be established by analysis of the set of identical triangles formed by radiating lines from the center of the polygon to each of the corners. The geometric surface area and open frontal area for the regular polygons are expressed by the following...

Now that you know how to find the perimeter of a polygon, are you curious about how to calculate its area? Then check out our area of a regular polygon calculator. Maybe you're interested in calculating the perimeter of a circle instead of a polygon? Then our circle perimeter calculator ...
of a point:Coordinates of a point in a coordinate plane tell us the position of the point on the plane. It is denoted by(x,y)wherextells us how many units the point is left or right from the origin(0,0)while theytells us how many units the point is up and down from the origin...
