We have a little more to discuss about triangles. First, there is an alternative formula for finding the A
rea of a triangle
when all three sides are known (and the height may not be known). Second comes the most infamous of all mathematical formulas since
Any idea of what equation that may be? It relates the three sides of a right triangle. If you still don't know, hang tight, we'll get to it shortly.

Whenever the three sides of a triangle are given the A
rea may be found by using an equation known as
If the lengths of the three sides of a triangle are a, b, & c
, then the A
rea of the triangle is given by the formula:
|A = √s(s - a)(s - b)(s - c)|
where s =12P
Clearly this equation may look a bit
However, once you understand what "s
" is (i.e.
, the s
emiperimeter), then it's really nothing more than a little bit of arithmetic.
