Question

A triangle has sides with lengths: 6, 1, and 9. How do you find the area of the triangle using Heron's formula?

Answer 1

Triangle doesn't exist because longest side `9>6+1`

Explanation:

The sides of triangle are `a=6, b=1\ &\ c=9`, we see that the longest side `c=9` is greater than the sum of other two sides `a+b=6+1=7` hence such a triangle doesn't exist
