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