There are 6 shapes on a 9x9 grid. Which shape is closest to the yellow 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: yellow rectangle at (4, 6)
Distance from target shape to brown square at (0, 2): 8
Distance from target shape to cyan trapezoid at (0, 5): 5
Distance from target shape to red trapezoid at (2, 5): 3
Distance from target shape to purple trapezoid at (7, 1): 8
Distance from target shape to blue rectangle at (6, 0): 8
Closest shape is the red trapezoid at (2, 5) with distance 3</think>
