A triangle has sides with lengths: 16, 11, and 9. How do you find the area of the triangle using Heron's formula?
Using Heron's formula is a two step process.
step 1 : find half of the triangles perimeter (s)
label the lengths of the 3 sides a , b and c.
In this case a = 16 , b = 11 and c = 9.
step 2 : Calculate the Area (A) using :
