If you look carefully you can see that the trapezia are actually bigger in the lower figure (the height of the smaller vertical edge is 1.8 in the upper and 2 in the lower).
Similarly the triangles are also bigger in the lower figure (same discrepancy in heights).
Great puzzle though.

It's the culmination of a series of cool calculations:
1 × 1 = 1
11 × 11 = 121
111 × 111 = 12321
1111 × 1111 = 1234321
11111 × 11111 = 123454321
111111 × 111111 = 12345654321
1111111 × 1111111 = 1234567654321

Now try it with different subjects.
"all the English 99% of school leavers need can be taught to them in a day."
"all the Geography 99% of school leavers need..."
"all the History 99% of school leavers need..."
Sort of a stupid argument.

My verdict on the 'woke' review of England's school curriculum? It isn't radical enough | Simon Jenkins
When I heard it was dumbing down education, my heart sank. In fact, it’s outspoken about the chaos of Michael Gove’s reforms and the changes needed, says Guardian columnist Simon Jenkins
