## Formula for Triangle Area

Earlier we find Area of Triangle by using the formula – Area of Triangle = $$\sqrt{s(s-a)(s-b)(s-c)}$$ where s = $$a+b+c\over 2$$ and a, b, c are the sides of the triangle. we have used this heron’s formula to find the area of a triangle when the lengths of its sides are given. Here, we will …
