First, we are going to use the law of cosines to find the length of the line segment FH:
Next, we are going to use the semi-perimeter formula:
Now that we have the semi-perimeter of our triangle, we can find its area using Heron's formula:
We can conclude that the area of the triangle <span>GHF is 2.7 </span>
