There are 3 shapes on a 9x9 grid. Which shape is closest to the red 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: red trapezoid at (2, 2)
Distance from target shape to green trapezoid at (8, 6): 10
Distance from target shape to blue square at (3, 5): 4
Closest shape is the blue square at (3, 5) with distance 4</think>
