There are 4 shapes on a 9x9 grid. Which shape is closest to the orange 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: orange trapezoid at (6, 7)
Distance from target shape to pink rectangle at (5, 8): 2
Distance from target shape to gray right_triangle at (8, 3): 6
Distance from target shape to blue square at (2, 2): 9
Closest shape is the pink rectangle at (5, 8) with distance 2</think>
