Heron's Formula -- from Wolfram MathWorldThis webpage is what you need.
An acute triangle, three perimeter side lengths are given and that is all that is given. No height, base or angles. Please give a formula to find the area of this type of triangle with only three perimeter numbers only, or explain how to find “b” from the perimeter. Area=1/2*b*h
Hi and thank you for your help.
That sight is over me, but i think i found it.
area= square root of (s(s-a)(s-b)(s-c))
So then will this give me the area from the perimeter?
