Question

Help please!! This is super confusing for me :(

Answer 1

1/20 mile

Explanation:

Let the Perimeter = P

20 (P) = 8 miles

P = 8/20 miles

Perimeter = 2 (Length) + 2 (width)

2 (3/20) + 2W = 8/20

2W = 8/20 - 6/20

2W = 2/20

W = 1/20

Answer 2

Explanation:

`Perimeter \ of \ block =(8)/(20)\\\\\\(3)/(20)+w+(3)/(20)+w = (8)/(20)\\\\\\(6)/(20)+2w=(8)/(20)\\\\\\2w=(8)/(20)-(6)/(20)\\\\\\2w=(2)/(20)\\\\\\w=(2)/(20*2)\\\\\\w=(1)/(20) \ mi`
