There are 6 shapes on a 7x7 grid. Which shape is closest to the blue 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: blue rectangle at (0, 2)
Distance from target shape to yellow right_triangle at (3, 1): 4
Distance from target shape to red square at (0, 4): 2
Distance from target shape to green trapezoid at (6, 3): 7
Distance from target shape to orange rectangle at (4, 0): 6
Distance from target shape to cyan trapezoid at (0, 5): 3
Closest shape is the red square at (0, 4) with distance 2</think>
