Is there a formula of finding the area of a triangle given three sides? Aside from using the law of cosine? Aside from 1/2 a c sinB 1/2 a b sinC 1/2 b c sinA given sides a,b,c = ??? i only need a formula help!

Its Heron's formula: Put $\displaystyle s=\frac{1}{2}(a+b+c)$, then area: $\displaystyle A=\sqrt {s(s-a)(s-b)(s-c)}$ RonL
Thanks agen captain!
