There are 3 shapes on a 9x9 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 (1, 3)
Distance from target shape to orange rectangle at (4, 5): 5
Distance from target shape to pink right_triangle at (1, 2): 1
Closest shape is the pink right_triangle at (1, 2) with distance 1</think>
