Answer:

Perimeter is  4+4√3

Step-by-step explanation:

P=x , Q=2x R=3x

x+2x+3x=180

6x = 180

x = 30

therefore, P=30

                 Q=60  

                 R=90

tan 30 = RQ/PR

∴∠1/√3 = RQ/4

RQ = 4 / √3

by pythagaros theroem

4² + ( 4/√3)² = PQ²

PQ = 8/√3

Perimeter = PQ+QR+PR

= 8/√3 + 4/√3 + 4

= 12/√3 + 4

= 4√3+12/√3

=4√3+4√3√3/√3

=√3(4+4√3)/√3

= 4+4√3
