There are 5 shapes on a 7x7 grid. Which shape is closest to the green trapezoid in terms of Manhattan distance? The final answer is the grid position of the closest shape like (row_index, column_index).
<think>Target shape: green trapezoid at (1, 0)
Distance from target shape to yellow rectangle at (2, 6): 7
Distance from target shape to cyan right_triangle at (0, 6): 7
Distance from target shape to gray square at (6, 2): 7
Distance from target shape to orange square at (4, 2): 5
Closest shape is the orange square at (4, 2) with distance 5</think>
