Answer:
 (L, W) ≈ (8.33, 4.17)
Step-by-step explanation:
Substituting for L, we have ...
 2(2W) +2W = 25
 6W = 25
 W = 25/6 ≈ 4.17
 L = 25/3 ≈ 8.33
The rounded "exact" solution is ...
 (L, W) = (8.33, 4.17)

Let the width be x
Since the question mentions the length is twice the width,
let the length be 2x
The total perimeter given is 25cm and as we know, perimeter for a rectangle :
=> P = 2(Length + width)
So,
25cm = 2(2x + x)
25 = 4x + 2x
25 = 6x
25/6 = x
4.166666667 = x
