Answer :
Take the square root of the larger denominator.
[tex] \sqrt{100} [/tex] = 10 - That is half of the length of the major axis
So, 10(2) = 20 is the length of the major axis
[tex] \sqrt{100} [/tex] = 10 - That is half of the length of the major axis
So, 10(2) = 20 is the length of the major axis
