Problem Statement
A trapezium is given with parallel bases having lengths and . Split it into two trapeziums by a cut, parallel to the bases, of length . We now want to divide the two new trapeziums, always by means of cuts parallel to the bases, in and trapeziums, respectively, so that all the trapezoids obtained have the same area. Determine the minimum possible value for and the lengths of the cuts to be made to achieve this minimum value.
