To calculate the area of this rectangle, you just have to count the number of colored squares. Ashley bought a square photo frame which is a regular polygon with 4 sides. For a triangle, multiply ½ by the length of the base and the height. This will work for triangles, regular and irregular polygons, convex or concave polygons. 2. All vertices of a regular polygon lie on a common circle (the circumscribed circle), i.e., they are concyclic points. Formulas to Calculate. Based on this, we can conclude that the area of a regular polygon is the sum of the nth number of areas of triangles, or rather S = nS∆. Any plane geometry figure that is bounded by straight lines connecting to form a closed shape is termed as the polygon. How to find the area of a regular polygon?
