Triangle Area and Height Problems

The video tutorial explains how to calculate the area of a composite shape consisting of a rectangle and two triangles. The instructor demonstrates the process by first calculating the area of the rectangle, then the area of each triangle using the formula for the area of a triangle. The final step involves summing these areas to find the total area of the shape, which is 255 square meters.
