There are 6 shapes on a 5x5 grid. Which shape is closest to the cyan 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: cyan rectangle at (0, 0)
Distance from target shape to orange square at (0, 3): 3
Distance from target shape to brown rectangle at (1, 4): 5
Distance from target shape to yellow right_triangle at (0, 4): 4
Distance from target shape to blue rectangle at (2, 4): 6
Distance from target shape to purple square at (4, 2): 6
Closest shape is the orange square at (0, 3) with distance 3</think>
