There are 5 shapes on a 10x10 grid. Which shape is closest to the brown rectangle 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 rectangle at (3, 2)
Distance from target shape to blue rectangle at (4, 8): 7
Distance from target shape to green right_triangle at (1, 1): 3
Distance from target shape to yellow trapezoid at (3, 5): 3
Distance from target shape to purple trapezoid at (2, 2): 1
Closest shape is the purple trapezoid at (2, 2) with distance 1</think>
