Dissection puzzle for area 49 to area 50

ver.1 : 7 pieces / 6, 6, 6, 6.5, 8, 8, 8.5

ver.2 : 6 pieces / 7, 7.5, 8, 8, 8.5, 10

ver.3 : 6 pieces / 7, 8, 8, 8.5, 8.5, 9

These are my designs for the dissection puzzle 49 to 50. They have same idea that the boundary pieces in the square of area 50 are put together to make the diagonal line in the square of area 49.

Ver.1 is the first design I made, but as I confused that 'stay under 7' means 'less than 7' or not, I made second version of design. Ver.3 is better than Ver.2 in the sence of 'roughly same area', but in actual puzzle, Ver.2 is better than Ver.3 because people can solve Ver.3 much faster than Ver.2.(I'm sure that people will put together yellow and blue piece first in solving Ver.3, which leads to the goal.)
