How to calculate ?To calculate the area of a polygon-shaped field, you need to break it down
into triangles and measure the lengths of the three sides of each triangle. If your field has n
corners, you can form n-2 triangles. For instance, if your field has 5 corners, you can create 5-2,
which is 3 triangles. Measure the lengths of the three sides for each triangular section using a
measuring tape. Then, enter these measured values into the input fields corresponding to each
triangle and click the "Calculate" button. Please input the side lengths in ascending order (side
1 < side 2 < side 3) to ensure proper calculations.
