There are 3 shapes on a 9x9 grid. Which shape is closest to the green 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: green trapezoid at (1, 2)
Distance from target shape to cyan rectangle at (0, 1): 2
Distance from target shape to red rectangle at (6, 8): 11
Closest shape is the cyan rectangle at (0, 1) with distance 2</think>
