Enter the coordinates of each vertex of your polygon. Points will be connected in order, and the last point will connect back to the first.
Grid: Each square = 1 unit
The Shoelace formula (also known as the surveyor's formula) calculates the area of a polygon by:
Formula: Area = ½|Σ(xiyi+1 - xi+1yi)|
This tool calculates polygon areas fast and simply. It starts with a default rectangle. The area for this shape is 12 square units.
The calculator works by letting you enter vertex coordinates. When you type in the numbers, the tool redraws the shape on a grid. A diagram shows each plotted point and side. The calculator uses the shoelace formula to compute the area.
Each input field asks for two numbers. The first is the x-coordinate. The second is the y-coordinate. The numbers are joined in order to create a shape. The last point connects back to the first.
The output shows the computed area in square units. It is displayed with four decimals. The tool also shows the steps of the shoelace formula. This helps you see how each term adds up.
This calculator works only with simple polygons. It needs at least three points. Enter correct numbers to avoid errors. The diagram may not display if you use non-numeric values.
This tool makes area calculations clear and simple. Follow the steps and see the shape drawn instantly. The detailed steps help you understand the computation process. Give it a try and see how easy it is to work with coordinates.
