The equation for finding the area of a rectangle is simply A = L * W. [3] This means that the area is equal to the length of the rectangle times its width. Method 2. Using the Area of the Rectangle. The figure shows a circle divided into 4 sectors and arranged in a certain way. What happens when we increase the number of sectors? Here we have divided the circle into 18 sectors so …Watch and learn how to find the area of a given sector of a circle. This tutorial will first show how to identify what fraction of the circle is occupied by......
