The question cannot be answered without further information. Have the rectangle and parallelogram the same length/ base? If not, what is the length of the rectangle and the base of the parallelogram?
Not possible... in order for it to have four right-angles, it would resemble a square or rectangle.
Almost but not quite because a rectangle has 4 equal right angles whereas a parallelogram has 2 equal opposite obtuse angles and 2 equal opposite acute angles.

A square is a special case of a parallelogram.
