The problem statement and test suite really need some improvement, here. It's a nice problem, though! I didn't assume that the three lengths given would form a triangle, and return a NaN if they don't.

Let a,b,c be the lengths of the sides of a triangle. The area is given by: Area=√p( p−a) (p−b)(p−c)
where p is half the perimeter
p= (a+b+c)/2
