How do I find the area of a triangle that has the side measurements of 6.2, 6.9, and 8.4? There are no angles given.
------------
You can use Heron's Law
---------
s = Perimeter/2 = (6.2+6.9+8.4)2
s = 10.75
a = 6.2
b = 6.9
c = 8.4
----

---------
Or, you can use the Cosine Law to find an angle, then find the area.
