A. Greater than
B. Less than
C. Equal to
D. Not related

Explanation

Area of square = Area of rectangular plate.
`therefore c^(2)=axxbimpliesc^(2)=ab`
Now by definition,
(a) `(I_(xR))/(I_(xS))=(b^(2))/(c^(2))[becauseIprop("area")^(2)]`
`therefore (I_(xR))/(I_(xS))=((b)/(c))^(2)lt1`
`therefore I_(xR)ltI_(xS)(because bltc)`
(b) `(I_(yR))/(I_(yS))=(a^(2))/(c^(2))`
`(I_(yR))/(I_(yS))=((a)/(c))^(2)gt1 (because agtc)`
(c ) `I_(zR)-I_(zS)prop(a^(2)+b^(2)-2c^(2))=a^(2)+b^(2)-2ab`
`=(a-b)^(2) [because c^(2)=ab]`
`(I_(zR)-I_(zS))gt0implies(I_(zR))/(I_(zS))gt1`
