    it says "use Heron's formula"

    so, first find the length of side c using law of cosine

    Can you show me how to use Heron's Formula to find the area? Ron Larson does not give an example.

    Ok. I got it. What does "drawing not to scale" mean? I see this statement often on old math exams.

    Not drawing something to scale means that you're not drawing it the correct size as it would actually be, especially in relation to something else.

    Ok. Not the exact model with the same measurements. Ok.
