There are 3 shapes on a 7x7 grid. Which shape is closest to the yellow rectangle in terms of Manhattan distance? The final answer is the grid position of the closest shape like (row_index, column_index).
<think>Target shape: yellow rectangle at (0, 2)
Distance from target shape to purple trapezoid at (2, 2): 2
Distance from target shape to gray trapezoid at (5, 0): 7
Closest shape is the purple trapezoid at (2, 2) with distance 2</think>
