This can be solved with Heron's formula, which states that the area of a triangle with side lengths $a, b$ and $c$ and semiperimeter $s$ has area$\sqrt{s(s-a)(s-b)(s-c)}$. Applying this we have the area of the triangle is $\sqrt{121\cdot 231\cdot 127\cdot 126} \approx 15926$. I hope this was helpful! :D
