nice problem!
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
