Final answer:
To find the area of the portion of the rectangle ABCD that falls outside the circle with center A, calculate the area of the rectangle and subtract the area of the circle.
Step-by-step explanation:
To find the area of the portion of the rectangle ABCD that falls outside the circle with center A, we need to calculate the area of the rectangle and subtract the area of the circle.
a) The area of the circle can be calculated using the formula A = πr^2, where r is the radius of the circle.
b) The area of the rectangle is calculated by multiplying its length and width.
c) The area of the shaded region is the difference between the area of the rectangle and the area of the circle.
d) The total area of ABCD is the sum of the area of the rectangle and the area of the shaded region.
