A triangle has sides with lengths: 2, 8, and 4. How do you find the area of the triangle using Heron's formula?
As there does not exists such a triangle, area cannot be determined.
According to Heron's formula if
Here sides are 2, 8 and 4. But to form a triangle sum of two smaller sides should be greater than largest side, which is not here. Hence, as there does not exists such a triangle, area cannot be determined.
