On a coordinate plane, parallelogram A B C D is shown. An altitude is drawn from point B to point E on side D C to form a right angle. The length of B E is 14.5. Point A is at (negative 10, 10), point B is at (4, 8), point C is at (10, negative 8), and point D is at (negative 4, negative 6). Segment BE is the altitude of parallelogram ABCD. BE is approximately 14.5 units long. What is the area of the parallelogram rounded to the nearest unit? square units
