i got AC thkns.....but what was the problem with long double??

i got a formula on the internet which helps to calculate the area of the triangle using three median. it is

1/3(sqrt(2(u^2v^2+u^2w^2+v^2w^2)-(u^4+v^4+w^4))

where u,v,w are the median of the triangle. using this i wrote the program...i got correct results for several test cases posted in this forum ...
