Answer:
A = [tex]\frac{1}{2}[/tex]bh
Step-by-step explanation:
The area of a triangle is defined as half the product of its base by its height.
A = [tex]\frac{1}{2}[/tex]bh
If you do not know the height but you know the length of the three sides of the triangle you can use Heron's formula to find the area
If the lengths of the sides are a, b, c then the area is
[tex]A = \sqrt{s(s-a)(s-b)(s-c)}[/tex]
Where
[tex]s =\frac{a+b+c}{2}[/tex]
