Question

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.

Answer 1

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

Answer 2

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
