There are 5 shapes on a 9x9 grid. Which shape is closest to the green 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: green square at (3, 3)
Distance from target shape to blue trapezoid at (6, 4): 4
Distance from target shape to brown square at (0, 4): 4
Distance from target shape to red rectangle at (2, 5): 3
Distance from target shape to cyan trapezoid at (6, 0): 6
Closest shape is the red rectangle at (2, 5) with distance 3</think>
