This MATLAB function calculates the area of a polygon shape, which is the sum of the areas of the solid regions that comprise the shape.
Compute the area of the polygon. a = polyarea(x,y) a = 4.0729 Input Arguments collapse all x-coordinates, specified as a vector, matrix, or multidimensional array. y-coordinates, specified as a vector, matrix, or multidimensional array. ...
Syntax a = areaint(lat,lon) a = areaint(lat,lon,ellipsoid) a = areaint(___,units)Description a = areaint(lat,lon) calculates the surface area of the polygon with geographic vertices lat and lon. This syntax references the coordinates to a unit sphere and returns a as the fraction ...
I have found this tutorial on topcoderGeometry Concept part 1. In the last section of the tutorial it discusses about area of a polygon. I have took the code and ran it in my IDE but it seems that it give me area = 0 for this coordinatesp = {{-1, -1}, {1, 1}, {1, -1}...

You are rewarded with a link to the Area of a Polygon Drawing Tool that can do all of this for you. It also accepts manual entry of coordinates.FormulasLet us play with some formulas!Let's start with a a simple triangle, with coordinates (x1, y1), (x2, y2), (x3, y3)...
longitudes into regular linear numbers (not degrees, etc.) then set up x and y coordinates at the vertices of the polygon you want (rectangle, triangle, or whatever), then pass into polyarea(). I believe it assumes that the polygon is 2D, flat, not bowed like on the surface of the ...
Find the perimeter and area of the polygon with the given vertices. J(−4,1),K(−4,−2),L(6,−2),M(6,1) Rectangles A rectangle is simply any polygon that contains four right angles. In the plane, we can check that a polygon is a rectangle if ...
