Answer:

RSTU=34

Explanation:

First we need to solve for RS using the Pythagorean theorem. So, that would be:

5²+12²=RS²

25+144=RS²

√169=RS

RS= 15

Now we need to calculate for ST:

If UST is a right angle triangle then again using the Pythagorean theorem-

3²+x²=5²

9+x²=25

x²=16

ST which is x=4

The last step is to add all of the sides together to get the perimeter.

12+3+4+15= 34

Hope this helps! :)
