Seem to work. Although could just state the elementary formulae used. Having said that, it depends upon the audience.

most people wouldn't know how to use the formula if i state it...

i tried the first method


the area for triangle 3,1,2 is 0 square units

because the semiperimeter is 3, thus when you apply it to Heron's Formula it has a 0 term in the squareroot, since it's all multiplication, any term multiply by 0 would produce 0. Thus my functions works fine.

Or for a more "obvious" reason, if you try to draw a 3-1-2 triangle, you'll find its height is 0.

As it has to be as 2+1 = 3.
