Question

how do you determine the area of a triangle...?

Answer 1

\[\frac{ 1 }{ 2 }\times base \times height\] or \[\frac{ 1 }{ 2 }a \times b \times sinC\]

Answer 2

Or ever more complicated: Heron's Formula:\[A = \sqrt{s(s-a)(s-b)(s-c)}\]Where \(s = \dfrac{a+b+c}{2}\). a, b, and c is length of side of triangle.
