There are 2 shapes on a 10x10 grid. Which shape is closest to the red 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: red trapezoid at (4, 5)
Distance from target shape to cyan right_triangle at (8, 7): 6
Closest shape is the cyan right_triangle at (8, 7) with distance 6</think>
