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 (9, 5)
Distance from target shape to purple trapezoid at (9, 2): 3
Distance from target shape to green rectangle at (0, 6): 10
Distance from target shape to red right_triangle at (9, 1): 4
Distance from target shape to orange rectangle at (7, 4): 3
Distance from target shape to brown rectangle at (6, 2): 6
Closest shape is the purple trapezoid at (9, 2) with distance 3</think>
