Quinn Collins · Answer 1

P = 2 (L + W)

P = 80

W = 1/3L

80 = 2 (L + 1/3L)

80 = 2 (3/3L + 1/3L)

80 = 2 (4/3L)

80 = 8/3L

80 * 3/8 = L

240/8 = L

30 = L ... length (L) is 30 ft

W = 1/3L

W = 1/3 (30)

W = 30/3

W = 10 < = = width (W) = 10 ft

Sterling Valenzuela · Answer 2

The length is 30ft one third of 30 is 10 so the width is 10 ft ... 30+30+10+10=80
