There are 6 shapes on a 9x9 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 (7, 3)
Distance from target shape to gray square at (3, 1): 6
Distance from target shape to red trapezoid at (8, 5): 3
Distance from target shape to blue square at (2, 3): 5
Distance from target shape to green rectangle at (4, 2): 4
Distance from target shape to pink square at (0, 1): 9
Closest shape is the red trapezoid at (8, 5) with distance 3</think>
