There are 3 shapes on a 9x9 grid. Which shape is closest to the cyan 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: cyan square at (7, 5)
Distance from target shape to purple trapezoid at (3, 8): 7
Distance from target shape to pink trapezoid at (0, 3): 9
Closest shape is the purple trapezoid at (3, 8) with distance 7</think>
