See solutions below
Step-by-step explanation:
1) From the diagram QS = RS
3x = 2x+2
3x-2x = 2
x = 2
Since RS = 2x+2
RS = 2(2)+2
RS = 4 + 2
RS = 6
2) RQ = RS + QS
RQ = 2x+2 + 3x
RQ = 5x+2
RQ = 5(2)+2
RQ = 12
3) PQ = PR
3y-1 = y+5
3y-y = 5+1
2y = 6
y = 3
PQ = 3y-1
PQ = 3(3)-1
PQ = 8
4) PR = y+5
PR = 3+5
PR = 8
5) PQSR = PQ + QR
PQSR = 8 + 12
PQSR= 20
