Answer:

2L + 2w = 120

L = 2w

---

2L + 2w = 120

2(2w) + 2w = 120

4w + 2w = 120

6w = 120

---

w = 20 ft

L = 40 ft

Answer:

L = 48, W = 24

Step-by-step explanation:

l = 2w

p = w + w + l + l

p = w + w + 2w + 2w

-

p = 6w

p = 120 + w

-

120 + w = 6w

120 = 5w

w = 24

-

24 + 120 = 144

P = 144

-

24 + 24 + l + l = 144

2l = 96

l = 48

-

Final Answer: L = 48, W = 24
