The paper considers the problem on extremal decomposition of a multiply connected domain $G\subset\mathbb C$ in the case where the associated quadratic differential is a perfect square. It is shown that in the case considered, the value of the functional for this extremal decomposition is the least one in a certain class of decompositions. Bibliography: 10 titles.
