There are 6 shapes on a 3x3 grid. Which shape is closest to the blue rectangle in terms of Manhattan distance? The final answer is the grid position of the closest shape like (row_index, column_index).
<think>Target shape: blue rectangle at (2, 2)
Distance from target shape to cyan trapezoid at (1, 0): 3
Distance from target shape to red rectangle at (1, 2): 1
Distance from target shape to orange trapezoid at (0, 2): 2
Distance from target shape to brown trapezoid at (2, 0): 2
Distance from target shape to yellow trapezoid at (1, 1): 2
Closest shape is the red rectangle at (1, 2) with distance 1</think>
