Calculate area from coordinates (Shoelace formula).
Perfect for non-rectangular plots of land.
Employs the surveyor's formula for accurate calculations from coordinates.
Add as many corners (points) as your plot has.
Calculate the area of any non-self-intersecting polygon (plot of land) using its corner coordinates. This is perfect for irregularly shaped plots where simple length-times-width doesn't apply. It uses the Shoelace (or Surveyor's) formula for accuracy.
Input the X and Y coordinates for each corner (vertex) of the plot in sequential order.
Use the '+ Add Point' button if your plot has more than four corners.
Click the 'Calculate Area' button to get the result in square units.
Enter the (X, Y) coordinates for each corner of your plot in order (clockwise or counter-clockwise).
