rectangle have so that its area is a maximum? (Enter your answers as a comma-separated list.) The xy-coordinate plane is given. A rectangle is inscribed inside a semicircle. The semicircle starts at (7,0), goes up and right, changes direction at (0,7), goes down and right, passes through the point labeled (x, y) which is a vertex of the rectangle, and ends at (7,0). The base of the rectangle is on the x-axis and the rectangle has vertices at (6,0), an unlabeled point in the third quadrant touching the semicircle, the point (x, y) touching the semicircle, and the point (6,0).
