There are 6 shapes on a 10x10 grid. Which shape is closest to the blue square in terms of Manhattan distance? The final answer is the grid position of the closest shape like (row_index, column_index).
<think>Target shape: blue square at (2, 9)
Distance from target shape to red rectangle at (4, 6): 5
Distance from target shape to gray rectangle at (0, 2): 9
Distance from target shape to cyan rectangle at (0, 9): 2
Distance from target shape to brown rectangle at (0, 8): 3
Distance from target shape to pink right_triangle at (9, 2): 14
Closest shape is the cyan rectangle at (0, 9) with distance 2</think>
