Area Of A TriangleThe area of a triangle, the coordinates of whose vertices are (x1, y1), (x2, y2) and (x3, y3) is | x1 (y2 – y3) + x2 (y3 – y1) + x3 (y1 – y2) | Remark: The area of ∆ABC can also be computed by using the following steps: Step I: Write the coordinates of the vertices A(x1, y1), B(x2, y2) and C(x3, y3) in three coloums as shown below and augment the … [Read more...] about Area Of A Triangle
