There are 3 shapes on a 7x7 grid. Which shape is closest to the orange square in terms of Manhattan distance? The final answer is the grid position of the closest shape like (row_index, column_index).
<think>Target shape: orange square at (3, 6)
Distance from target shape to red trapezoid at (0, 6): 3
Distance from target shape to cyan rectangle at (5, 6): 2
Closest shape is the cyan rectangle at (5, 6) with distance 2</think>
