from your previous questions, we know the larger number must be under the variable x which is the horizontal axis.

if the major axis is 22, then a = 11. Similarly, b = 9

therefore a

^{2}= 121 and b^{2}= 81c

^{2}= 121 - 81 = 40c = 2√10

The first denominator is 121 and the second denominator is 81. The distance from the center to the foci is represented by c and c equals 2 Times Square root 10
