remember that the sum of any two sides of a triangle has to be greater than the third side, so let's try the possible 3 numbers that have a sum of 8.

6 1 1 - no

5 1 2 - no

5 2 1 - no

4 1 3 - no

4 2 2 - no

4 3 1 - no

3 1 4 - no

3 2 3 - yes

any others would simply be permutations of the above.

Using Heron's formula --- http://www.mathopenref.com/heronsformula.html

area = √(4(1)(1)(2))

= 2√2
