Methods to Find the Area of a Triangle
Area of a triangle can be found using three different methods. The three different methods are discussed below
Method 1
When the base and altitude of the triangle are given.
Area of the triangle, A = bh/2 square units
Where b and h are base and altitude of the triangle, respectively.
Method 2
When the length of three sides of the triangle are given, the area of a triangle can be found using the Heron’s formula.
Therefore, the area of the triangle is calculated using the equation,
A = [tex]\tt\sqrt{s(s-a) (s-b) (s-c)}
s(s−a)(s−b)(s−c)[/tex]
Where a, b, c are the side lengths of the triangle and s is the semi perimeter
The value of s is found using the formula
[tex]\tt{ s = \frac{a+b+c}{2}}[/tex]
