There are 2 solutions because the line x+2y = 12 and the circle intersect at two locations. One point of intersection is (0,6). So this suggests choice B is the answer; however, the point (12,0) is not a solution.
It works for x+2y = 12 since 12+2(0) = 12. But the point (12,0) is not on the circle. The furthest to the right we go is (6,0).
The answer would be 64 m2 because it said the length is the same as width so it is basically like a square. The perimeter is 32/4=8 because there are 4 sides in the rectangle. 8 times 8 is 64
