Building the 'Moonhouse': Q&A with artist Mikael Genberg - Space
If you cut off the end of that rectangle, you make it smaller, 2 * 3 and a separate nub of size 1 * 2
Move the nub up to the top:
n^2 - 1
The more direct answer is to look at a rectangle with sides of n + 1 and n - 1, let’s go with n = 2
So, that’s a rectangle with sides 2 and 4.
And you are left with almost a square. One less than the square of side n.

The basic answer is that you cross-multiply the values in each factor:
(n - 1)(n + 1)
