Answer:
22 units
Step-by-step explanation:
The perimeter of a rectangle is 2(width + length)
In this case width = 2z + 2 and length = 3z + 3
replacing everything known:
110 = 2(2z + 2 + 3z + 3)
110/2 = (5z + 5)
55 = 5z + 5
55 - 5 = 5z
50 = 5z
10 = z
Segment PQ is the same as SR = 2z + 2
Replacing z = 10
PQ = 2(10) + 2
