Answer:
The length of the side of the polygon is [tex]36\ units[/tex]
Step-by-step explanation:
we know that
the formula to calculate the distance between two points is equal to
[tex]d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}[/tex]
we have
[tex]A(7,-18)\\B(7,18)[/tex]
substitute the values
[tex]d=\sqrt{(18+18)^{2}+(7-7)^{2}}[/tex]
[tex]d=\sqrt{(36)^{2}+(0)^{2}}[/tex]
[tex]d=36\ units[/tex]
