There are 6 shapes on a 6x6 grid. Which shape is closest to the brown 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: brown trapezoid at (2, 4)
Distance from target shape to gray rectangle at (1, 1): 4
Distance from target shape to cyan square at (2, 2): 2
Distance from target shape to purple trapezoid at (1, 2): 3
Distance from target shape to yellow square at (1, 0): 5
Distance from target shape to green right_triangle at (0, 3): 3
Closest shape is the cyan square at (2, 2) with distance 2</think>
