Question 976475: Find the area of the triangle.
Carry your intermediate computation to atleast four decimal places. Round to the nearest tenth.
The side measures are 13 mi, 16mi , 18mi (not a right triangle)****

You can put this solution on YOUR website!
The side measures are 13 mi, 16mi , 18mi
------------
You can solve for an angle using the Cosine Law, then Area = b*h*sin(angle) where the angle is between the 2 sides.
-----------
Or use Heron's Law:
Area = sqrt%28s%2A%28s-a%29%2A%28s-b%29%2A%28s-c%29%29 where a, b & c are the sides and s = (a+b+c)/2
