Area of the Triangles are denoted by the following formulas:
1. Basic Formula,
A = 12 * base * height, where base is known and height is
perpendicular to the base.
2. 2 sides and an included angle, A = 12 * a * b * sin 4, where a and b are two known
sides and 4 is an included angle of the two known sides.
3. Hero's Formula, A = √s(s — a)(s — b)(s — c), where S = ½ (a+b+c), where a, b
and c are the three known sides of the triangle.
