We are given

[tex] x^2+4y^2=36 [/tex]

Since, this is equation of ellipse

so, firstly we will change it into standard equation of ellipse

[tex] \frac{(x-h)^2}{a^2}+\frac{(y-k)^2}{b^2}=1 [/tex]

now, we can change our equation into this form

[tex] x^2+4y^2=36 [/tex]

we divide both sides by 36

we get

[tex] \frac{x^2}{36}+ \frac{4y^2}{36} =1 [/tex]

now, we can simplify it

[tex] \frac{x^2}{6^2}+ \frac{y^2}{3^2} =1 [/tex]

now, we can compare and find 'a' and 'b'

[tex] a=6, b=3 [/tex]

Since, shorter value is b

so, length of minor axis is 2b

length of minor axis is 2*3

The length of minor axis is 6...........Answer
