To minimize the perimeter of a rectangular area with a fixed area of 32 m², the AM-GM inequality (arithmetic mean ≥ geometric mean) can be applied: for a rectangle with sides x and y where xy = 32, the perimeter P = x + 2y is minimized when x = 2y, yielding the minimum perimeter of 24 meters. This demonstrates how the AM-GM inequality provides an efficient method for solving optimization problems in real-world scenarios.
