WebWe can calculate the area of an oriented triangle using the shoelace formula. The shoelace formula or algorithm is a mathematical algorithm used to determine the area of a simple polygon whose vertices are described by their cartesian coordinates on a plane. In our case we have a triangle. Steps to find area of Polygon WebIt is called the shoelace formula because of the constant cross-multiplying for the coordinates making up the polygon, like tying shoelaces. [1] It is also sometimes called the shoelace method. It is also known as Gauss's area formula, after Carl Friedrich Gauss. It has applications in surveying and forestry, [2] among other areas.
