There are 5 shapes on a 10x10 grid. Which shape is closest to the red rectangle in terms of Manhattan distance? The final answer is the grid position of the closest shape like (row_index, column_index).
<think>Target shape: red rectangle at (9, 6)
Distance from target shape to cyan rectangle at (4, 7): 6
Distance from target shape to gray rectangle at (6, 5): 4
Distance from target shape to orange right_triangle at (2, 4): 9
Distance from target shape to yellow rectangle at (1, 3): 11
Closest shape is the gray rectangle at (6, 5) with distance 4</think>
