A parallelogram is a rectangle that has been pushed sideways — sheared — and shearing never changes area: slice a triangle off one end and it fits exactly onto the other. So the area is still base times height, provided h is the perpendicular distance between the two parallel sides, not the length of the slanted side. Using the slant side is the single most common error with this formula.
