Using Pythagoras theorem,

For the right-angled triangle that contains x

=> $$5^2 = (\sqrt{13})^2 + x^2$$

=> => $$x^2 = 5^2 - 13$$

=> $$x = \sqrt{12}$$

For the right-angled triangle that contains y

=> $$5^2 = (\sqrt{11})^2 + y^2$$

=> => $$y^2 = 5^2 - 11$$

=> $$y = \sqrt{14}$$

Hence y is greater than x

@AE

Quantity A is $$\sqrt{12}$$ instead of 12 and Quantity B is $$\sqrt{14}$$ instead of 14.
