Optimization of Triangle and Square Areas

The video tutorial addresses an optimization problem involving a 100-foot wire. The wire is cut into two parts, with one part forming an equilateral triangle and the other a square. The goal is to determine the cut point that minimizes the combined area of the triangle and square. The tutorial derives the area formulas for both shapes and combines them to find the optimal solution.
