There are 4 shapes on a 9x9 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 (8, 1)
Distance from target shape to gray square at (2, 3): 8
Distance from target shape to brown trapezoid at (7, 8): 8
Distance from target shape to yellow rectangle at (3, 2): 6
Closest shape is the yellow rectangle at (3, 2) with distance 6</think>
