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