There are 6 shapes on a 10x10 grid. Which shape is closest to the orange 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: orange trapezoid at (7, 3)
Distance from target shape to green trapezoid at (0, 4): 8
Distance from target shape to pink trapezoid at (3, 6): 7
Distance from target shape to blue right_triangle at (4, 5): 5
Distance from target shape to red square at (2, 7): 9
Distance from target shape to cyan square at (6, 1): 3
Closest shape is the cyan square at (6, 1) with distance 3</think>
