This geometry video tutorial explains how to calculate the area of the shaded region of circles, rectangles, triangles, and squares. The first example explains how to calculate the area of the shaded region of a square inside of a rectangle. The second example involves a circle inside of a rectangle and third example involves a circle inside of another circle. Other examples include a right triangle inside of a circle, a square inscribed in a circle, and a circle inscribed in a equilateral triangle as well as a rhombus inside of a square.
