WebHow many diagonals exist for a 7-sided polygon? The number of diagonals can be found by: n• (n-3)/2. So in this case :7• (7 - 3)/2 = 7•4/2 = 14 diagonals. WebTo get the area of the whole polygon, just add up the areas of all the little triangles ("n" of them): Area of Polygon = n × side × apothem / 2. And since the perimeter is all the sides = n × side, we get: Area of Polygon = perimeter × apothem / 2. A Smaller Triangle. By cutting the triangle in half we get this:
