how to find the perimeter of a polygon with coordinates

The sum of the length of all sides of a closed figure is called the perimeter of the figure. Here, the perimeter (P) is the sum of the three sides: P = 13.42 + 6.71 + 15 ≅ 35.1 In this lesson, we will deal with the idea of finding area and perimeter when you don't know the dimensions of an object, just the locations of the corners on a coordinate plane. Before adding geometry attributes (length, area, perimeter) to a line or polygon shapefile or X / Y Coordinates to a point shapefiles in QGIS, make sure the shapefiles are in reference to a projected coordinate system such as a UTM Zone, or a State Plane Coordinate System (Refer to this post for the differences between a projected coordinate system and a geographic coordinate system). For a polygon, the perimeter is the sum of its side lengths. study Each of the sides in the example (other than the blue easy one) were calculated by building a right triangle that had the unknown side as its hypotenuse (the side opposite the right angle).
