There are 4 shapes on a 10x10 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, 3)
Distance from target shape to green right_triangle at (7, 9): 11
Distance from target shape to purple trapezoid at (3, 8): 6
Distance from target shape to orange trapezoid at (1, 7): 5
Closest shape is the orange trapezoid at (1, 7) with distance 5</think>
