A typical chessboard consists of 8 x 8 = 64 one by one squares. Of course, there are many more squares on an 8 x 8 chessboard of other configurations. If you increase the number of one by one squares to a 12 by 12 chessboard, how many rectangles would be on this 12 x 12 chessboard? Again, we are looking for the number of rectangles.
