There are 6 shapes on a 10x10 grid. Which shape is closest to the blue 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: blue trapezoid at (4, 7)
Distance from target shape to yellow square at (1, 4): 6
Distance from target shape to pink rectangle at (9, 2): 10
Distance from target shape to cyan rectangle at (5, 6): 2
Distance from target shape to green right_triangle at (2, 1): 8
Distance from target shape to purple rectangle at (4, 0): 7
Closest shape is the cyan rectangle at (5, 6) with distance 2</think>
