Video Summary

The problem involves a large square divided into two unequal squares and two equal rectangles, with a shaded quadrilateral whose vertices are midpoints of the square sides. The given area of the shaded quadrilateral is 3. It is determined that this shaded area represents 1/8 of the total square's area, thus the entire square has an area of 24. Consequently, the unshaded portion of the square is 21. The solution also notes that the problem can be approached by considering the square's side length derived from the total area of 24.
