There are 4 shapes on a 7x7 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 (2, 2)
Distance from target shape to brown right_triangle at (4, 2): 2
Distance from target shape to blue square at (5, 6): 7
Distance from target shape to gray rectangle at (2, 4): 2
Closest shape is the brown right_triangle at (4, 2) with distance 2</think>
