There are 4 shapes on a 10x10 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 (8, 1)
Distance from target shape to blue trapezoid at (3, 5): 9
Distance from target shape to green right_triangle at (2, 2): 7
Distance from target shape to cyan rectangle at (5, 6): 8
Closest shape is the green right_triangle at (2, 2) with distance 7</think>
