<think>Target shape: orange square at (4, 7)
Distance from target shape to pink right_triangle at (0, 6): 5
Distance from target shape to purple rectangle at (1, 7): 3
Distance from target shape to green square at (9, 1): 11
Distance from target shape to brown trapezoid at (1, 3): 7
Distance from target shape to red right_triangle at (6, 2): 7
