Area of a rectangle (which includes squares) is length times width. Since both the length and width are the same on a square, A = 9 cm x 9 cm = 81 cm^2. (It's kind of cool how the units work out the way they're supposed to--we always talk about square inches, square centimeters, etc. It's nice to see that mathematically we really do get square units.).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
