There are 5 shapes on a 10x10 grid. Which shape is closest to the yellow 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: yellow rectangle at (5, 8)
Distance from target shape to purple square at (2, 1): 10
Distance from target shape to orange rectangle at (0, 7): 6
Distance from target shape to gray right_triangle at (9, 5): 7
Distance from target shape to brown trapezoid at (8, 4): 7
Closest shape is the orange rectangle at (0, 7) with distance 6</think>
