There are 6 shapes on a 10x10 grid. Which shape is closest to the cyan 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: cyan trapezoid at (7, 5)
Distance from target shape to red square at (3, 6): 5
Distance from target shape to pink trapezoid at (2, 2): 8
Distance from target shape to blue rectangle at (2, 3): 7
Distance from target shape to purple right_triangle at (4, 2): 6
Distance from target shape to yellow square at (6, 8): 4
Closest shape is the yellow square at (6, 8) with distance 4</think>
