An archaeologist discovers a rectangular stone tablet with a perimeter of 72 units. What is the largest possible area of this tablet?

When a plaque from the past surfaces—shaped like a rectangle, weathered by time, and bearing a measured perimeter—curiosity naturally sparks. What does a stone tablet with a perimeter of 72 units reveal about geometry, history, and human ingenuity? More than just an artifact, it opens a window into ancient problem-solving and the elegant patterns hidden in nature.

Understanding how to calculate the maximum area of a rectangle with a fixed perimeter reveals a timeless mathematical truth—optimal shapes often follow precise, predictable rules. For a rectangle with perimeter 72, the largest area isn’t found at random lengths but at balanced proportions—specifically, when the rectangle approximates a square.

How to find the largest area: A clear, beginner-friendly explanation

To determine the maximum area, begin by defining variables: let length = L and width = W. The perimeter is given by:

P = 2L + 2W = 72

Simplify:
L + W = 36

Final Thoughts

Area A is:
A = L × W

To maximize A, substitute W = 36 – L:
A = L × (36 – L) = 36L – L²

This quadratic equation A = –L² + 36L has a maximum at its vertex, found by L = –b/(2a) from standard form:
**L = –36 /
