There are 5 shapes on a 9x9 grid. Which shape is closest to the red square in terms of Manhattan distance? The final answer is the grid position of the closest shape like (row_index, column_index).
<think>Target shape: red square at (3, 0)
Distance from target shape to pink rectangle at (2, 6): 7
Distance from target shape to orange trapezoid at (6, 0): 3
Distance from target shape to gray rectangle at (1, 3): 5
Distance from target shape to blue right_triangle at (3, 8): 8
Closest shape is the orange trapezoid at (6, 0) with distance 3</think>
