There are 5 shapes on a 10x10 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 (4, 2)
Distance from target shape to orange rectangle at (9, 9): 12
Distance from target shape to pink trapezoid at (3, 2): 1
Distance from target shape to green square at (9, 5): 8
Distance from target shape to brown rectangle at (2, 5): 5
Closest shape is the pink trapezoid at (3, 2) with distance 1</think>
