Answer:
33.8
Step-by-step explanation:
1) Use Phythagoras theorem to get RS ↓
[tex]9.1 ^{2} + 6 ^{2} = 118.81 \\ \sqrt{118.81 } = 10.9[/tex]
2) RS = RQ
therefore, to get the perimeter, you'll have to total up the sides of the triangle ↓
[tex]rs + rq +qt + ts \\ = 10.9 + 10.9 + 6 + 6 \\ = 33.8[/tex]
Hope this helps =)
