Understanding Area and Unit Squares

The video tutorial explains the concept of area by comparing two figures on a screen. It introduces the idea of a unit square as a standard measure of area and demonstrates how to calculate the area of each figure by counting the number of unit squares that fit within their boundaries. The tutorial concludes by comparing the areas of the two figures, showing that the purple figure has twice the area of the blue figure.
