There are 6 shapes on a 8x8 grid. Which shape is closest to the orange 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: orange rectangle at (3, 0)
Distance from target shape to green square at (7, 5): 9
Distance from target shape to yellow rectangle at (4, 2): 3
Distance from target shape to purple rectangle at (2, 5): 6
Distance from target shape to cyan rectangle at (0, 2): 5
Distance from target shape to red trapezoid at (6, 2): 5
Closest shape is the yellow rectangle at (4, 2) with distance 3</think>
