We study the problem of partitioning a rectangle S with a set of interior points Q intorectangles by introducing a set of line segments of least total length. The set of partitioning line segments must include every point in Q. Since this problem is computationally intractable (NP-hard), several approximation algorithms for its solution have been developed. In this paper we show that the legnth of an optimal guillotine partition is not greater than 1.75 times the length of an optimal rectangular partition. Since an optimal guillotine partition can be obtained on O(n^5) time, we have a polynomial time approximation algorithm for finding near-optimal rectangular partitions.
