There are 5 shapes on a 10x10 grid. Which shape is closest to the gray square in terms of Manhattan distance? The final answer is the grid position of the closest shape like (row_index, column_index).
<think>Target shape: gray square at (2, 9)
Distance from target shape to cyan right_triangle at (1, 0): 10
Distance from target shape to brown square at (7, 0): 14
Distance from target shape to yellow rectangle at (5, 3): 9
Distance from target shape to green right_triangle at (0, 6): 5
Closest shape is the green right_triangle at (0, 6) with distance 5</think>
