This seems like this could be a complicated, with special cases for whether the polygon is convex or maybe other considerations. But as long as the polygon is “simple,” i.e. the sides meet at vertices but otherwise do not intersect each other, then there is a general formula for the ...
Area of a Regular Polygon Area of a Regular Pentagon Formula Lesson Summary FAQs Activities How do you find the area of a 5-sided polygon? If the apothem isn't known, it should be solved first using the apothem formula. Then the regular polygon formula can be applied. Multiply th...
The Area of an Irregular Polygon Examples Lesson Summary Frequently Asked Questions What is the formula to calculate the area of a polygon? There is no general formula to calculate the area of an irregular polygon. However, knowing the formulas to calculate the are of regular polygons can hel...
Rearranging the terms (and changing signs) we get the so-called "shoelace formula":−2×Area = x1y2 + x2y3 + x3y1 − x2y1 − x3y2 − x1y3In GeneralIn general (for an n-sided simple polygon), using absolute values || we have:...
We wish to find a general formula for the area of a circumscribed polygon based on the number of sidesnand the radius of the circler.The diagram shows a circumscribed pentagon; however, all calculations should be done as if the num...
Where “a” is the length of the octagon sides. It is not possible to find the area of an irregular octagon using this formula. So, to find its area, it is divided into other regular polygons. Then, the areas of all polygons should be added to get its area. ...
