There are 6 shapes on a 10x10 grid. Which shape is closest to the brown 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: brown rectangle at (6, 5)
Distance from target shape to yellow square at (9, 2): 6
Distance from target shape to blue square at (8, 9): 6
Distance from target shape to cyan square at (9, 6): 4
Distance from target shape to pink trapezoid at (5, 7): 3
Distance from target shape to orange right_triangle at (4, 4): 3
Closest shape is the pink trapezoid at (5, 7) with distance 3</think>
