Calculator for area and perimeter of closed polygon with three sides
This calculator is useful to determine the area of a three sided closed plygon when its coordinates Northing (Y coordinate) and Easting (X coordinate) are given. Please make sure that the polygon is a convex polygon. The area is given by the following formula.
Area = 0.5 x Absolute value of ((X1Y2 – Y1X2) + (X2Y3 – Y2X3) + (X3Y1 – X1Y3) )
Please enter the values in the appropriate units mentioned in the form given below and start calculations.
