In this program, we first accept the number of sides and then accept the co-ordinates of each vertex. where, S is the length of any side N is the number of sides π is PI, approximately 3.142 NOTE: The area of a polygon that has infinite sides is the same as the area a circle. equilateral and equal angles i.e. how to implement this programatically: A Polygon is a closed plane figure having three or more sides. = (9 * 4) / 4 * Tan(0.785) = 4.5 * 0.95 = (1.501 * 12) / 2 = 36/ 3.996 An apothem is also used sometimes to find the area of a regular polygon. Area is the space inside the perimeter/boundary of space, and its symbol is (A). The outputs are: r radius of inscribed circle, R radius of circumscribed circle and the area A of the polygon. Area =21.552 This will work for triangles, regular and irregular polygons, convex or concave polygons. 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. 2. Let's use this polygon as an example: Coordinates. You can find this expression under Geometry. = 3 * 0.808 = 3* Cos (0.63) Area of a quadrilateral. every time we find one of these, we chop it off, calculate its area (easy peasy, wont explain formula here) and make a new polygon with one less side (equivalent to polygon with this triangle chopped off). = (0.5) * 3² * Sin(2 * 3.14 / 5) Active 2 years, 10 months ago. The area of the polygon is Area = a x p / 2, or 8.66 multiplied by 60 divided by 2. It returns a list containing the elements from each part. Now, for each line segment, work out the area down to the x-axis. = 5.90 * 5 * Tan(0.63) It is simple when the edges don't intersect, so if the polygon isn't crossed. = ((3)² * 4) / (4 * Tan(3.14 / 4)) Area of a trapezoid. However, it is much harder to find the area of an irregular shape. Enter the length of the sides for each triangle you use; up to 10 of them. As the polygon is a pentagon having five sides, where each side (s) measures 12 cm, its perimeter (p) is = (5 x s) = (5 x 12) = 60 cm It is one of the simplest shapes, and … Also, we’ll use some basic operation of linear algebra.
