A polyomino is a connected collection of unit squares where the unit squares create a continuous path for the first square to the last square. Consecutive squares in the path must share a side. The smallest polyomino that has one hole uses 7 unit squares, as shown. How many unit squares are in the smallest polyomino that has two holes? (A hole is a unit square that is not part of the polyomino but is surrounded on all four sides by squares that are part of the polyomino.
