Answer 3

This is basically the pythagorean theorem.
Where side a^2 + side b^2 = hypotenuse^2

And they squared every sides by literally making it into a square.

Answer 4

XY and YZ are the 2 sides, and XZ is the hypotenuse.

The square area gives you the length of the triangle's sides' squared value so that's already done.
