submit answer

Explanation:

Step1: Identify coordinates of vertices

From the graph:
$S=(0,-1)$, $T=(3,3)$, $U=(-2,3)$, $R=(-5,-1)$

Step2: Calculate side lengths (horizontal)

Length of $SR$ and $UT$:
$\vert -5 - 0 \vert = 5$

Step3: Calculate slant side length

Use distance formula for $ST$:
$\sqrt{(3-0)^2 + (3-(-1))^2} = \sqrt{3^2 + 4^2} = \sqrt{9+16} = \sqrt{25} = 5$

Step4: Compute perimeter

Parallelogram perimeter: $2\times(\text{horizontal side}+\text{slant side})$
$2\times(5+5)=20$

Answer:

20
