There are 6 shapes on a 9x9 grid. Which shape is closest to the pink 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: pink rectangle at (8, 2)
Distance from target shape to blue rectangle at (2, 7): 11
Distance from target shape to yellow rectangle at (0, 6): 12
Distance from target shape to green right_triangle at (8, 7): 5
Distance from target shape to purple square at (5, 0): 5
Distance from target shape to orange trapezoid at (4, 8): 10
Closest shape is the green right_triangle at (8, 7) with distance 5</think>
