The sides of a triangle are $a$, $b$, and $c$ inches, where $a$, $b$, and $c$ are integers and $a\le b\le c$. If $c$ is given, find the number of triangles possible.

I don't know from where to start this question. Please provide the solution.

This question was merged with What is the number of triangles with integer sides, given the length of the longest side? [closed] because it is an exact duplicate of that question.

  • $\begingroup$ This is not really a duplicate of the cited question. That question asks for triangles where $a\le b\color{#C00}{\lt}c$. $\endgroup$ – robjohn Nov 20 '17 at 12:13
