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