Find the area of the following ellipse use = 3.14 and round to nearest tenth. a = 7 in.; b = 9 in. area = sq. in.

Area = PI x a x b

area = 3.14 x 7 x 9

area = 197.8 sq. in.

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
