Calculating Areas of Shaded Regions

The video tutorial explains how to calculate the area of a shaded region common between two quadrants of circles with a radius of 10 cm each. The process involves finding the area of one quadrant and subtracting the area of a triangle formed within it. This area is then doubled to account for both quadrants, resulting in a total shaded area of 57 cm².
