There are 6 shapes on a 10x10 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 (3, 8)
Distance from target shape to brown trapezoid at (5, 4): 6
Distance from target shape to green square at (4, 4): 5
Distance from target shape to red trapezoid at (2, 5): 4
Distance from target shape to yellow square at (2, 3): 6
Distance from target shape to pink rectangle at (4, 0): 9
Closest shape is the red trapezoid at (2, 5) with distance 4</think>
