Video Summary

The problem involves determining the area of a shaded region within a square of 100 cm². By dividing the large square into smaller sections using vertical and horizontal lines, it is found that the shaded region consists of identical triangles. Each triangle is half of the rectangle it is in, which itself is half of a quadrant. The process involves calculating one quarter of the quadrant area, further halved for the rectangle, then the triangle, and considering four such triangles. The total shaded area is therefore 25 cm², corresponding to answer choice B.
