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 (2, 1)
Distance from target shape to orange trapezoid at (0, 0): 3
Distance from target shape to pink square at (0, 9): 10
Distance from target shape to cyan rectangle at (4, 4): 5
Closest shape is the orange trapezoid at (0, 0) with distance 3</think>
