Opposite sides of a parallelogram are equal, so the perimeter is twice the sum of two adjacent sides — the same structure as the rectangle's, because a parallelogram is a rectangle that has been leaned over. Note that leaning changes the area (height shrinks) but never the perimeter: the sides keep their lengths as the shape shears.
