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 (8, 2)
Distance from target shape to red trapezoid at (2, 9): 13
Distance from target shape to gray square at (1, 1): 8
Distance from target shape to cyan square at (7, 7): 6
Distance from target shape to orange right_triangle at (9, 8): 7
Distance from target shape to blue right_triangle at (0, 0): 10
Closest shape is the cyan square at (7, 7) with distance 6</think>
