There are 5 shapes on a 6x6 grid. Which shape is closest to the red 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: red rectangle at (2, 5)
Distance from target shape to orange rectangle at (5, 2): 6
Distance from target shape to purple trapezoid at (1, 2): 4
Distance from target shape to cyan trapezoid at (4, 4): 3
Distance from target shape to brown right_triangle at (0, 3): 4
Closest shape is the cyan trapezoid at (4, 4) with distance 3</think>
