Answer 2

The perimeter is 11.12.

We use the distance formula to find the length of each segment that makes up the quadrilateral:

For RS:
$d=\sqrt{(7-3)^2+(-2--1)^2}=\sqrt{4^2+(-2+1)^2}=\sqrt{16+(-1)^2} \\ \\=\sqrt{16+1}=\sqrt{17}=4.12$

For ST:
$d=\sqrt{(7-5)^2+(2-2)^2}=\sqrt{2^2+0^2}=\sqrt{4+0}=\sqrt{4}=2$

For TU:
$d=\sqrt{(5-5)^2+(-1-2)^2}=\sqrt{0^2+(-3)^2}=\sqrt{0+9}=\sqrt{9}=3$

For UR:
$d=\sqrt{(5-3)^2+(-1--1)^2}=\sqrt{2^2+0^2}=\sqrt{4+0}=\sqrt{4}=2$

This gives us a perimeter of 2+3+2+4.12 = 11.12
