It can be visualized using a single stepped triangular shape made of squares. Imagine n columns, where the first column has 1 square, the second 2, and so on, until the nth column has n squares. Inside this shape, you can fit a large inscribed triangle whose area is n^2/2. The remaining spaces consist of n half-squares, each with area 1/2, which together add
