The video tutorial explains how to determine the dimension of a triangle using the area formula. It begins by identifying the given information: the area, the unknown base, and the height. The tutorial then demonstrates how to apply the area formula, A = 1/2 * base * height, to find the missing base. The process involves substituting known values into the formula, simplifying the equation, and solving for the base using division. The tutorial concludes with a step-by-step calculation to find that the base is 2.5 units.
