How to find area of polygon

Solution. On the left we can see that the figure is composed of a rectangle with area of 2 ⋅ 5 = 10 square units plus another with area 2 and a third with area 1 square unit. So the total area is. 10 + 2 + 1 = 13 square units. On the right we can see that the area is composed of two rectangles and a single square: 2(2 ⋅ 3) + 1 = 13.

A regular polygon has all angles equal and all sides equal, otherwise it is irregular : Regular : Irregular . Concave or Convex. A convex polygon has no angles pointing inwards. More precisely, no internal angle can be more than 180°. If any internal angle is greater than 180° then the polygon is concave.To calculate the area of a regular polygon, multiply ½ x p (the perimeter) x a (the apothem, or the distance from the center of the polygon to the midpoint of any side). If the polygon is irregular, you’ll need to divide it up into regular shapes (e.g., a rectangle and a triangle), find the area of each part, and add them together. ...Given a GeoPandas's GeoDataFrame containing a series of polygons, I would like to get the area in km sq of each feature in my list. This is a pretty common problem, and the usual suggested solution in the past has been to use shapely and pyproj directly (e.g. Calculating area in km² for Polygon in WKT using Python and robinkraft/projected_area ... To calculate the polygon area, you measure side lengths, put them into the table below, then split the polygon into non-overlapping triangles, measure needed diagonals, put them into the table, and you're done.
