There are 4 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 (0, 2)
Distance from target shape to yellow right_triangle at (4, 1): 5
Distance from target shape to gray rectangle at (5, 9): 12
Distance from target shape to red rectangle at (6, 7): 11
Closest shape is the yellow right_triangle at (4, 1) with distance 5</think>
