A classical result of Honsberger states that the number of incongruent triangles with integer sides and perimeter $n$ is the nearest integer to $n^{2}/48$ ( $n$  even) or $(n+3)^{2}/48$ ( $n$  odd). We solve the analogous problem for $m$ -gons (for arbitrary but fixed $m\geq 3$ ) and for polygons (with arbitrary number of sides).
