Hint: Given a parallelogram with sides 'a' and 'b' with an acute angle 'x', the area of this parallelogram is ab%2Asin%28x%29


Note: if you're given an obtuse angle, you can use the idea that the adjacent angles are supplementary to find the supplement acute angle. If each angle is a right angle, then the area is simply ab (ie we're now dealing with a rectangle).
