An interesting problem with an interesting solution. This problem has a wrinkle that the author left out: when you declare that the sum of the four triangle is fixed (ie 200), you require that the original square grow or shrink depending on where you cut the side. This becomes obvious if you try the 2 extreme cases: cut the square at the end or in the middle.
