There are 6 shapes on a 10x10 grid. Which shape is closest to the purple trapezoid in terms of Manhattan distance? The final answer is the grid position of the closest shape like (row_index, column_index).
<think>Target shape: purple trapezoid at (8, 5)
Distance from target shape to red square at (0, 7): 10
Distance from target shape to yellow trapezoid at (9, 8): 4
Distance from target shape to gray rectangle at (2, 0): 11
Distance from target shape to green square at (3, 7): 7
Distance from target shape to cyan square at (1, 9): 11
Closest shape is the yellow trapezoid at (9, 8) with distance 4</think>
