A certain window is three times as long at it is wide. If its perimeter is 28 feet, what are its dimensions in terms of length by width?

The OA is C.
I'm really confused with this PS question. Experts, any suggestion? I don't undestarnd it.
I know that its perimeter will be, P = 2L + 2W = 28, also I know that L = 3W. But I don't have it clear, what can I do for solve it. Thanks in advance.
