There are 4 shapes on a 9x9 grid. Which shape is closest to the yellow 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: yellow trapezoid at (1, 4)
Distance from target shape to gray rectangle at (0, 8): 5
Distance from target shape to cyan square at (5, 1): 7
Distance from target shape to orange right_triangle at (3, 2): 4
Closest shape is the orange right_triangle at (3, 2) with distance 4</think>
