    If this is a Heron's formula situation, I'm guessing it means 'semi-perimeter.' . . .

    if you use herons formula you get the area and then you can solve for the height then solve for an angle and your all set

    @Decart what information are you using to determine that an angle needs to be found?

    there is nothing else to solve area angles

    The question is asking for 's' - until we know what the variable s represents, we shouldn't be making assumptions. Yes, we could completely solve the triangle if we wanted to, but I'd rather answer the actual question.

    @Timtime can you clarify what the problem is asking for? Is it referring to semi-perimeter?

    \[s=\frac{ a+b+c }{ 2 }\]

    So 's' means area?
