So, the length is two times the width. We will make two formulas

P = 2L + 2W    , where L is length and W is width
L =2W+2

So, since you know that L = 2W and P = 28cm, you can plug that into the first formula. When you do that, you'd get

(28) = 2(2W+2) + 2W
28 = 4W + 4 + 2W
28-4 = 6W
24 = 6W
W = 4,

So, the Width would be 4 cm, the length would be 2(4) + 2 which is 10
