Understanding Area and Fractions in Geometry

The video tutorial explains how to calculate the area of a square and its shaded region. It begins by defining the dimensions of a square and calculating its total area. The focus then shifts to understanding and calculating the shaded area using fractions and rectangles. An alternative method for calculating the shaded area is also presented, emphasizing different approaches to solving the problem.
