There are 5 shapes on a 10x10 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 (8, 8)
Distance from target shape to gray rectangle at (6, 6): 4
Distance from target shape to pink right_triangle at (2, 0): 14
Distance from target shape to brown square at (9, 9): 2
Distance from target shape to yellow right_triangle at (9, 2): 7
Closest shape is the brown square at (9, 9) with distance 2</think>

<answer>(9, 9)</answer>
