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