Geometry and Triangle Properties

The video tutorial explains how to calculate the area of an equilateral triangle with sides of length six. It involves splitting the triangle into two right triangles, using special right triangle rules to find the hypotenuse, and then calculating the area using the base and height. The final result is rounded to 15.6 square units.
