The Foundation

Find the area of any triangle using its side lengths a, b, and c using the semi-perimeter 's'.

The Master Equation

Area = โˆš[s(s-a)(s-b)(s-c)]

Where s = (a + b + c) / 2

How to use:

  • Step 1: Identify all three side lengths (a, b, c).
  • Step 2: Calculate the semi-perimeter (s) by summing sides and dividing by 2.
  • Step 3: Subtract each side from 's' (s-a, s-b, s-c).
  • Step 4: Multiply these four values: s, (s-a), (s-b), and (s-c).
  • Step 5: Take the square root of the result.
