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