There are 5 shapes on a 10x10 grid. Which shape is closest to the blue 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: blue trapezoid at (2, 7)
Distance from target shape to brown square at (5, 4): 6
Distance from target shape to red right_triangle at (5, 6): 4
Distance from target shape to purple trapezoid at (9, 4): 10
Distance from target shape to green square at (3, 1): 7
Closest shape is the red right_triangle at (5, 6) with distance 4</think>
