There are 6 shapes on a 10x10 grid. Which shape is closest to the cyan 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: cyan square at (2, 4)
Distance from target shape to red rectangle at (8, 4): 6
Distance from target shape to purple square at (7, 0): 9
Distance from target shape to brown right_triangle at (7, 3): 6
Distance from target shape to yellow square at (7, 7): 8
Distance from target shape to blue trapezoid at (3, 5): 2
Closest shape is the blue trapezoid at (3, 5) with distance 2</think>
