Suzanna explains how to find the area of a rectangle inscribed in a right triangle. She identifies the rectangle's sides as X and Y, and uses the properties of similar triangles to establish a relationship between the sides. By comparing the ratios of corresponding sides, she derives an equation to calculate the area of the rectangle, ultimately finding it to be 55. The video concludes with a recap of the problem-solving process.
