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?

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.
