1 dzień temu · Calculation Formula. For a general quadrilateral, the area can be calculated if the coordinates of its vertices are known. One common approach is to divide the quadr. ilateral into two triangles and sum their areas. The formula for the area of a triangle given its vertices \ ( (x_1, y_1), (x_2, y_2), (x_3, y_3)\) is:
