There are 6 shapes on a 10x10 grid. Which shape is closest to the brown 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: brown trapezoid at (7, 3)
Distance from target shape to gray square at (0, 8): 12
Distance from target shape to orange right_triangle at (2, 5): 7
Distance from target shape to purple right_triangle at (0, 7): 11
Distance from target shape to cyan rectangle at (5, 5): 4
Distance from target shape to red rectangle at (5, 7): 6
Closest shape is the cyan rectangle at (5, 5) with distance 4</think>
