There are 5 shapes on a 10x10 grid. Which shape is closest to the orange 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: orange square at (5, 4)
Distance from target shape to red rectangle at (1, 7): 7
Distance from target shape to yellow right_triangle at (8, 0): 7
Distance from target shape to cyan trapezoid at (7, 8): 6
Distance from target shape to brown rectangle at (4, 1): 4
Closest shape is the brown rectangle at (4, 1) with distance 4</think>
