Problem Statement

A line in the plane of a triangle TT is called an equalizer if it divides TT into two regions having equal area and equal perimeter. Find positive integers a>b>c,a>b>c, with aa as small as possible, such that there exists a triangle with side lengths a,b,ca,b,c that has exactly two distinct equalizers.
