Write down the formula for finding the area of a regular polygon. To find the area of a regular polygon, all you have to do is follow this simple formula: area = 1/2 x perimeter x apothem.[1] X Research source Here is what it means: Perimeter = the sum of the lengths of all the sides[2] X Research source Apothem = a segment that joins the polygon's center to the midpoint of any side that is ...Find the apothem of the polygon. If you're using the apothem method, then the apothem will be provided for you. Let's say you're working with a hexagon that has an apothem with a length of 10√3.Find the perimeter of the polygon. If the perimeter is provided for you, then you're nearly done, but it's likely that you have a bit more work to do. If the apothem is provided for you and you know that you're working with a regular polygon, then you can use it to find the perimeter. Here's how you do it:[4] X Research source Think of the apothem as being the "x√3" side of a 30-60-90 ...Plug the apothem and the perimeter into the formula. If you're using the formula area = 1/2 x perimeter x apothem, then you can plug in 120 for the perimeter and 10√3 for the apothem. Here is what it will look like:[5] X Research source area = 1/2 x 120 x 10√3 area = 60 x 10√3 area = 600√3Simplify your answer. You may need to state your answer in decimal instead of square root form. Just use your calculator to find the closest value for √3 and multiply it by 600. √3 x 600 = 1,039.2. This is your final answer.[6] X Research sourceIf you list the points in a clockwise order instead of counterclockwise, you will get the negative of the area. Hence this can be used as a tool to identify the cyclic path or sequence of a given set of points forming a polygon. Thanks Helpful 1 Not Helpful 0This formula computes area with orientation. If you use it on a shape where two of the lines cross like a figure eight, you will get the area surrounded counterclockwise minus the area surrounded clockwise. Thanks Helpful 0 Not Helpful 0- 1.5M
Jul 14, 2024 · If you want to calculate the regular polygon parameters directly from equations, all you need to know is the polygon shape and its side length: 1. Area. area = n × a² × cot(π/n)/ 4 ; Where n- number of sides, a - side length. Other equations, which use parameters such as the circumradius or perimeter, can also be used to determine the area.
6 days ago · Determine the polygon area given side lengths and some diagonals by splitting the polygon into triangles. Then find the area with the given three sides (SSS) equation (you can learn the origin of this formula with our Heron's formula calculator). Calculate the area of polygons using other formulas – e.g., for a scalene triangle or a ...
