Answer:
674.34cm^2
Step-by-step explanation:
the diameter of the cirtcle is equal to the rectangles side (which is 20cm)
To answer this question you have to find the circumfrance of the circle, multiply it by 2, the subtract it from the area of the rectangle.
-the area of the rectangle is 800. (40*20)
-the circumfrance of one circle is 62.83 (1/2 of 20 times pi)
- So 800-(62.83x2). 800-125.66
The answer is 674.34
