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

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.
