There are 6 shapes on a 10x10 grid. Which shape is closest to the red 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: red trapezoid at (8, 2)
Distance from target shape to brown trapezoid at (8, 8): 6
Distance from target shape to orange trapezoid at (9, 7): 6
Distance from target shape to yellow right_triangle at (2, 7): 11
Distance from target shape to cyan square at (0, 9): 15
Distance from target shape to blue rectangle at (3, 8): 11
Closest shape is the brown trapezoid at (8, 8) with distance 6</think>
