Abstract
Alon, N. and D.J. Kleitman, Partitioning a rectangle into small perimeter rectangles, Discrete
Mathematics 103 (1992) 111119.
We show that the way to partition a unit square into kZ + s rectangles, for s = 1 or s = 1, so as
to minimize the largest perimeter of the rectangles, is to have k  1 rows of k identical
rectangles and one row of k + s identical rectangles, with all rectangles having the same
perimeter. We also consider the analogous problem for partitioning a rectangle into n
rectangles and describe some possible approaches to it.
