There are 6 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 (4, 6)
Distance from target shape to gray trapezoid at (9, 1): 10
Distance from target shape to cyan square at (5, 7): 2
Distance from target shape to brown rectangle at (6, 8): 4
Distance from target shape to pink rectangle at (5, 0): 7
Distance from target shape to yellow square at (4, 0): 6
Closest shape is the cyan square at (5, 7) with distance 2</think>
