As we can see, the sum of the two radius of the two identical circles is 4; therefore the circle's radius is 2.
The height of the rectangle can also be found out in the same way:
By this, we can get the height and the length of the rectangle:
To gain the area, we multiply the rectangle's length with it height.
8 × 4 = 3 2
Therefore, 3 2 is the area of the rectangle.
