There are 5 shapes on a 7x7 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 (0, 2)
Distance from target shape to orange trapezoid at (2, 6): 6
Distance from target shape to purple right_triangle at (1, 4): 3
Distance from target shape to blue trapezoid at (0, 4): 2
Distance from target shape to yellow trapezoid at (4, 5): 7
Closest shape is the blue trapezoid at (0, 4) with distance 2</think>
