Lubicz says the last step of the solution, getting the side length of 6 after the side length of 8 has already been determined, is uncertain because of deterioration of the papyrus. The scribe arrived at the correct solution to the problem. However, the question alone (given a square with side 10, find the sidelengths of two squares in ratio 3:4 that have a combined area equal to the area of the side 10 square) shows an awareness of the equality of the areas of the two smaller sides with the larger side for a 3:4:5 triplet. This is the essence of Pythagoras theory.
