She found that by folding the paper twice she could obtain a length of 6 inches. The first fold which is shown below, produces a 2 1/2-inch length. She then used this length and the 8 1/2-inch length to produce a 6-inch length. She continued to experiment with the sheet of paper and found that she could obtain many other lengths.
