The video tutorial explains how to find the area and perimeter of an equilateral triangle. It begins with the formula for calculating the area, which is base times height divided by two. The base and height of the triangle are identified, and the area is calculated as 15 square millimeters. The tutorial then moves on to calculating the perimeter by adding all sides of the triangle, resulting in a perimeter of 18 millimeters. The video emphasizes the properties of an equilateral triangle, where all sides are equal, and provides a step-by-step guide to solving these geometric problems.
