Calculating Area of Triangles

The video tutorial explains how to calculate the total area of a shape made up of six identical triangles. Each triangle has a height of 10 feet and a base of 6 feet. The area of one triangle is calculated using the formula (base * height) / 2, resulting in 30 square feet. To find the total area of the shape, the area of one triangle is multiplied by six, giving a total area of 180 square feet. The tutorial includes a step-by-step explanation and visualization of the process.
