Rectangle from two corners

The sides of a rectangle are parallel to the coordinate axes. Two of its opposite corners are given: $(x_1, y_1)$ and $(x_2, y_2)$. Find the perimeter and the area of the rectangle.

A single line with four integers $x_1$, $y_1$, $x_2$, (each at most in absolute value, , ).

A single line with two integers: the perimeter and the area.

The side lengths are the absolute differences of the coordinates: $|x_2 - x_1|$ and $|y_2 - y_1|$. The corners may come in any order, so a length must stay positive even when the difference is negative.
