herons formula?

3. anonymous

What is 's' ?

4. anonymous

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

5. anonymous

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?

7. anonymous

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?

10. anonymous

$s=\frac{ a+b+c }{ 2 }$

11. anonymous

i got 14m^2

12. anonymous

So 's' means area?

13. anonymous

yea i got the answer right

14. anonymous

thank you
