Magda cut out two identical isosceles triangles, each of which had a perimeter of 100 cm. First, from these triangles she formed a quadrilateral by placing them together by their legs. Then from them she formed a quadrilateral by placing them together by their bases. In the first case she obtained a quadrilateral with a perimeter 4 cm shorter than in the second case. Determine the lengths of the sides of the cut-out triangles.
