There are 6 shapes on a 10x10 grid. Which shape is closest to the yellow square in terms of Manhattan distance? The final answer is the grid position of the closest shape like (row_index, column_index).
<think>Target shape: yellow square at (0, 7)
Distance from target shape to pink square at (4, 4): 7
Distance from target shape to red trapezoid at (7, 5): 9
Distance from target shape to cyan rectangle at (9, 4): 12
Distance from target shape to brown trapezoid at (9, 0): 16
Distance from target shape to purple rectangle at (5, 5): 7
Closest shape is the pink square at (4, 4) with distance 7</think>
