There are 6 shapes on a 9x9 grid. Which shape is closest to the brown 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: brown square at (4, 5)
Distance from target shape to cyan square at (4, 2): 3
Distance from target shape to blue trapezoid at (2, 1): 6
Distance from target shape to orange trapezoid at (1, 4): 4
Distance from target shape to yellow rectangle at (3, 7): 3
Distance from target shape to gray rectangle at (7, 6): 4
Closest shape is the cyan square at (4, 2) with distance 3</think>
