# I Want Me Less Unit Squares

Denote $$u(s)$$ as a function of the minimum number of unit squares that can be formed in a rectangular grid with semiperimeter $$s$$ where $$s\in \mathbb Z^+\setminus\{1\}$$ (for example, $$u(6)=5$$). Find $$u(1153)$$.

Clarification:

• Unit square is a square with side 1.
