There are 5 shapes on a 9x9 grid. Which shape is closest to the green 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: green rectangle at (0, 2)
Distance from target shape to red trapezoid at (5, 5): 8
Distance from target shape to brown right_triangle at (0, 1): 1
Distance from target shape to yellow rectangle at (4, 1): 5
Distance from target shape to cyan square at (3, 0): 5
Closest shape is the brown right_triangle at (0, 1) with distance 1</think>
