An isosceles triangle has a perimeter of 15 m. Find all the integral possibilities for the lengths of the sides in meters. Hint the sum of the lengths of any two sides of a triangle must exceed the third side.

If the 3rd side has length 1, then the sides are
1,7,7
similarly, if it grows in steps of 2, the sides are
3,6,6
5,5,5,
7,4,4
But then two sides would not exceed the length of the third side so I am thinking
1, 1, 13
2, 2, 11
3, 3, 9
