Join the two brocades together to make
one large square cushion-cover.
How can you do this so as to mutilate
the material as little as possible?
Make the cuts
only along the lines that divide the little chequers.
I cut the two squares in the manner desired into
four pieces that would fit together and form another larger square,
taking care that the pattern should match properly, and when I had
finished I noticed that two of the pieces were of exactly the same
area; that is, each of the two contained the same number of chequers.
Can you show how the cuts were made in accordance with these conditions?
