Answer:
11
Step-by-step explanation:
6 + 3 = 9
8 + 3 = 11
Plug in 4 for x and solve equation like so. c=2
Answer: l = 60 ft and w = 30 ft
P = 2(l + w)
180 = 2(l + w)
Let x = width of his yard
Let 2x = length of his yard





l = 2x = 30(2) = 60 ft
Check:
180 = 2(l + w)
180 = 2(60 + 30)
180 = 2(90)
180 = 180
LS = RS
