Hey! The correct answer is 55.
Perimeter = 1020 m
let width be = X
let length be = 20 + 6 (X)
perimeter of rectangle = 2 ( length + width )
1020 = 2 ( 20 + 6 X + X )
1020 = 2 ( 20 + 7 X )
1020 = 40 + 14 X
14 X = 1020 - 40
14 X = 980
X = 980 / 14 = 70
width = X = 70 meters
length = 20 + 6X = 20 + 6 ( 70 )
= 20 + 420
= 440 meters

Answer: 720 ways
Step-by-step explanation:
We know that the total number of ways to arrange n things in a row in order is given by Permutations.
i.e. The total number of ways to arrange n things in a row= n!
Therefore, the number of ways to arrange 6 unique CD's in order along a shelf will be :

Hence, there are 720 ways to arrange 6 unique CD's in order along a shelf.
