There are 4 shapes on a 9x9 grid. Which shape is closest to the brown trapezoid 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 trapezoid at (8, 5)
Distance from target shape to cyan right_triangle at (2, 1): 10
Distance from target shape to red trapezoid at (5, 7): 5
Distance from target shape to pink rectangle at (2, 2): 9
Closest shape is the red trapezoid at (5, 7) with distance 5</think>
