[tex]\bigg( \dfrac{Length_1}{Length_2} \bigg)^2 = \bigg( \dfrac{Area_1}{Area_2}\bigg)
[/tex]
[tex]\bigg( \dfrac{Length_1}{Length_2} \bigg)^2 = \bigg( \dfrac{6 \pi }{150 \pi }\bigg)
[/tex]
[tex]\bigg( \dfrac{Length_1}{Length_2} \bigg)^2 = \bigg( \dfrac{1 }{25}\bigg)
[/tex]
[tex]\dfrac{Length_1}{Length_2} = \sqrt{ \dfrac{1}{25} }
[/tex]
[tex]\dfrac{Length_1}{Length_2} = \dfrac{1}{5} [/tex]
