If the ellipse `(x^2)/(a^2-7)+(y^2)/(13=5a)=1` is inscribed in a square of side length `sqrt(2)a` , then `a` is equal to `6/5` `(-oo,-sqrt(7))uu(sqrt(7),(13)/5)` `(-oo,-sqrt(7))uu((13)/5,sqrt(7),)` no such a exists

A

B

`(0oo,-sqrt7) uu (sqrt7 , (13)/(5))`

C

`(-oo,-sqrt7)uu ((13)/(5), sqrt7)`

D

no cush 'a' exists
