There are 6 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 (0, 4)
Distance from target shape to blue right_triangle at (0, 0): 4
Distance from target shape to brown trapezoid at (4, 4): 4
Distance from target shape to orange trapezoid at (3, 2): 5
Distance from target shape to green right_triangle at (0, 3): 1
Distance from target shape to cyan trapezoid at (2, 0): 6
Closest shape is the green right_triangle at (0, 3) with distance 1</think>
