Problem Statement

A regular hexagon has positive integer side length. A laser is emitted from one of the hexagon’s corners, and is reflected off the edges of the hexagon until it hits another corner. Let aa be the distance that the laser travels. What is the smallest possible value of a2a^2 such that a>2019a > 2019?
You need not simplify/compute exponents.
