First, you can get the area of an equilateral triangle by just noting that it’s made up of two triangles. Regular polygon calculator is an online tool to calculate the various properties of a polygon. Note as well, there are no parenthesis in the "Area" equation, so 8.66 divided by 2 multiplied by 60, will give you the same result, just as 60 divided by 2 multiplied by 8.66 will give you the same result. The solution is an area of 259.8 units. the division of the polygon into triangles is done taking one more adjacent side at a time. Area of a square. You need the perimeter, and to get that you need to use the fact that triangle OMH is a triangle (you deduce that by noticing that angle OHG makes up a sixth of the way around point H and is thus a sixth of 360 degrees, or 60 degrees; and then that angle OHM is half of that, or 30 degrees).

The area of a polygon is defined as the region occupied irrespective of its shape, like a parallelogram, triangle, quadrilateral, square, rectangle or rhombus. Now I have a new column called Area_calculation which contains total area for each polygon. As shown below, this means that we must find the perimeter (distance all the way around the hexagon) and the measure of the apothem using right triangles and trigonometry. And you don’t have to start at the top of the polygon — you can start anywhere, go all the way around, and the numbers will still add up to the same value. They assume you know how many sides the polygon has. Use the one that matches what you are given to start. Perimeter: Perimeter of a polygon is the total distance covered by the sides of a polygon. Importantly, we’ve chosen a point for calculating the areas. The area is the quantitative representation of the extent of any two-dimensional figure. Interior angles of polygons.
