It is D because if you look at the graph every 5 years the acres decrease by 20
If the circumference is half of the perimeter than the area for both circles would be half of them find one circles area and half it
(xA+xB)/2, (yA+yB)/2 = (4,3)
(xA+xB)/2 = 4
(-2+xB) = 8 --> xB = 8+2 --> xB = 10
(yA+yB)/2 = 3
(6+yB) = 6 --> yB = 6-6 --> yB = 0
B = (10,0)
