P= 2 ( L+W)
22= 2(6+ W) you plug in what you know and solve for W
22= 2(6+5)
22=2(11)
22=22
W= 5 cm
Answer:
The answer o your question is y=8
Answer:
54
Step-by-step explanation:

Length x width = area
width=x
length=2x
2x*x=50
2x^2=50
x^2=25
x=5
width=5
length=2x5=10
Y= 13.5
13.5 = 1.8c
13.5/1.8 = 1.8c/1.8
c = 7.5
