There are 3 shapes on a 5x5 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, 4)
Distance from target shape to purple rectangle at (2, 1): 4
Distance from target shape to cyan square at (2, 2): 3
Closest shape is the cyan square at (2, 2) with distance 3</think>
