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