<think>Target shape: purple rectangle at (1, 1)
Distance from target shape to brown rectangle at (2, 2): 2
Distance from target shape to blue rectangle at (0, 1): 1
Distance from target shape to pink square at (3, 3): 4
Distance from target shape to yellow trapezoid at (6, 9): 13
Closest shape is the blue rectangle at (0, 1) with distance 1</think>
