There are 5 shapes on a 5x5 grid. Which shape is closest to the yellow 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: yellow rectangle at (4, 4)
Distance from target shape to blue trapezoid at (3, 2): 3
Distance from target shape to green rectangle at (0, 0): 8
Distance from target shape to red rectangle at (2, 4): 2
Distance from target shape to cyan trapezoid at (0, 4): 4
Closest shape is the red rectangle at (2, 4) with distance 2</think>
