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