On the first line in the solution to this question it says 2x.5a^2.
If it's a triangle it should only be .5a^2?
Is it because the card is folded? If so isn't it just a heavier triangle with COM in the same place?

yeah its because it is folded. so there are two triangle on the same place. so .5a^2+ .5a^2.
