Step-by-step explanation:

The graph shows all of the sides of the figure aligned with the axes except side ST. Its length can be found using the distance formula:

d = √((x2 -x1)² +(y2 -y1)²)

d = √((7 -(-5))² +(-2 -3)²) = √(144 +25) = 13

Then the perimeter is the sum of the side lengths:

13 + 4 + 12 + 9 = 38

The perimeter of STUV is 38 units.
