Question

perimeter help

Answer 1

The perimeter of the quadrilateral, is the sum of the four sides lengths.

To find each sides length, use pythag.

Answer 2

Like what UnkleRhaukus said, just use Pythagorean Theorem.

\(a^2+b^2=c^2\)

Note that \(\overline{ZW} = \overline{WX}\), just to save little works.
