PLZ HELP ME NEED THIS FAST WILL GIVE BRAINLIEST
OleMash [197]

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

180=2(2x+x)

\frac{180}{2}=\frac{2(2x+x)}{2}

90=3x

\frac{90}{3} =\frac{3x}{3}

x=30ft

l = 2x = 30(2) = 60 ft

Check:

180 = 2(l + w)

180 = 2(60 + 30)

180 = 2(90)

180 = 180

LS = RS
