Problem Statement

A regular hexagon in the plane is called sweet if its area is equal to 11. Is it possible to place 20000002000000 sweet hexagons in the plane such that the union of their interiors is a convex polygon of area at least 19000001900000?
Remark: A subset SS of the plane is called convex if for every pair of points in SS, every point on the straight line segment that joins the pair of points also belongs to SS. The hexagons may overlap.
