There are 5 shapes on a 7x7 grid. Which shape is closest to the orange 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: orange trapezoid at (2, 5)
Distance from target shape to cyan right_triangle at (5, 0): 8
Distance from target shape to blue rectangle at (5, 4): 4
Distance from target shape to gray right_triangle at (1, 1): 5
Distance from target shape to green square at (2, 0): 5
Closest shape is the blue rectangle at (5, 4) with distance 4</think>
