Answer:the length is 12 and the width is 24 ( I think)

Step-by-step explanation:Answer:W=1 4/5 feet

L= 2 2/5 feet

Step-by-step explanation:3L = 4W L = 4W/3

2L+2W = 8 2/5

Substitute L

2(4W/3)+2W = 8 2/5

8W/3+2W = 8 2/5

multiply both sides by 3

8W+6W = 24 6/5

14W = 25 1/5

Divide both sides by 14

14W/14 = (25 1/5)/14

W = (126/5)/14 = 9/5 = 1 4/5

Substitute for W

L = 4(1 4/5)/3

L = (4)(9/5)/3 = (36/5)/3 = 12/5 = 2 2/5
