Answer:
30
Step-by-step explanation:
The perimeter of this rectangle is calculated by adding width to length and that multiplied by 2
2*(3x+2x+2) = 54 do inside the parenthesis first
2*(5x+2) = 54 multiply inside the parenthesis by 2
10x + 4 = 54 subtract 4 from both sides
10x = 50 divide both sides by 10
x = 10
The length for PS is 3x
3*10 = 30
