Put the centers of each at the origin of a cartesian coordinate system. The circle will be \"x%5E2%2By%5E2=%2821%2F2%29%5E2\". Cut the 18 inch length in half, so it be 9 inch. Now put your attention onto quadrant 1. One coordinate on the circle would be 9; what will the other coordinate be? Will it be less than or equal to \"13%2F2\"? If yes, then the rectangle will fit. If no, then the rectangle will not fit.\r
