Information..
Sum of angles of \(\triangle RWV = x+2x+3x=180...x=30\), so it is a 30-60-90 triangle. As RV=2, RW=1, and WV=\(\sqrt{3}\)
We require the length of RS, ST, TV
(1) The perimeter of ΔRST is \(3 + \sqrt{3}\).
We cannot find sides from it.
(2) RW = RS = ST = TV
Rw=1, so RW = RS = ST = TV=1.
Perimeter of the 5-sided figure RSTVW = \(RW + RS + ST + TV+WV=1+1+1+1+\sqrt{3}=4+\sqrt{3}\)

Hi Bunuel,
Just because I want to be sure... the first statement is insufficient because we can't assume that triangle RWV is congruent with the triangle RVT even when in the diagram they look similar?
