1. Of all triangles with integer sides which has the smallest perimeter and 3 different length sides.

2. Determine the total number of different integer sided triangles there are with perimeter 15.

(In reply to re: Resist by Jer)

Um?
from #1 "3 different length sides".

I carried that thought into #2 assuming that was also the intent of "different integer sided triangles".

If replication of integers is allowed then I also offer:
7-7-1, 7-6-2, 7-5-3, 7-4-4, 6-6-3, 6-5-4 and 5-5-5.
