It is a rectangle. Reason: A parallelogram has opposite sides of same length.The same applies to a rectangle also with one more additional fact that all angles are right angles. It can't be a rhombus or square as both the closed figures have all sides of same length.And it is impossible to construct a four-sided figure with only one angle as right angle and opposite sided of same length.So,it is a rectangle.And all four angles are right angles It is a rectangle.
