The Triangular Room

Geometry Level 4

Daniel is standing in the middle of an equilateral triangle-shaped room. He wants to touch all three walls and return back to the center of the room. If the shortest distance between Daniel and a wall is 11, then dd is the shortest distance Daniel has to walk to complete his task. Find d2d^2.

Details and Assumptions

Walking to a vertex of the triangular room counts as touching both walls adjacent to the vertex.
