Question

A triangle has sides with lengths: 4, 12, and 4. How do you find the area of the triangle using Heron's formula?

Answer 1

There is no such triangle, since `4+4 < 12`

Explanation:

In order for lengths `a`, `b` and `c` to form a triangle with non-zero area, all of the following must hold:

`a+b > c`

`b+c > a`

`c+a > b`
