Explanation:
We know all three triangles have integer sides, since the third sides is the difference of the perimeter and the other two sides, all integers.
So the sides are
The sides have to satisfy the triangle equality, which is the sum of any two side lengths is larger than the third. Let's write the three inequalities:
So we have
so
