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 the side length and the apo...
Irregular Polygons and Irregular Shapes The Area of an Irregular Polygon Examples Lesson Summary Frequently Asked Questions What is the formula to calculate the area of a polygon?

Regular IrregularThe Example PolygonLet's use this polygon as an example:CoordinatesThe first step is to turn each vertex (corner) into a coordinate, like on a graph:Area Under One Line SegmentNow, for each line segment, work out the area down to the x-axis....
As someone pointed out in the comments, in practice you might want to subtract the minimumxvalue from all thexcoordinates and the minimumyvalue from all theycoordinates before using the formula. Why’s that? If you add a constant amount to each vertex, you move your polygon but you don’...
Area of Triangle a Formula What is an Area of a triangle? The area of a polygon is the number of square units covered by the polygon. The area of a triangle is determined by multiplying the base of the triangle and the height of the triangle and then divides it by 2. The division ...
please correct them. It is also important to note that this function does not apply to the autocross polygon. It is important to note that both PointX and PointY are the node coordinates of the polygon, but this formula has eliminated one of the same nodes in the first tail, as a point...
