This puzzle comes from a Chinese puzzle book. This is the translation of the puzzle:
There are 4 sticks 10 cm long and 4 sticks 5 cm long. How to form three squares of equal area with these sticks?
Despite trying my best, I could not figure this out. Any help in this problem is appreciated. Thank you.
