Move the nub up to the top:
If you cut off the end of that rectangle, you make it smaller, 2 * 3 and a separate nub of size 1 * 2
Why is Jack Smith arguing that presidents should not have full immunities as Trump is requesting?
The more direct answer is to look at a rectangle with sides of n + 1 and n - 1, let’s go with n = 2
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:
So, that’s a rectangle with sides 2 and 4.
