    Answer:

    L=130 while W=39

    Step-by-step explanation:

    Let’s setup some equations.

    W=.3L  from first sentence

    2L+2W=338 from second sentence

    I’m going to plug equation 1 into equation 2:

    2L+2[.3L]=338

    2L+.6L=338

    2.6L=338

    L=338/2.6

    L=130

    so W=.3L=.3(130)=39

    Answer L=130 while W=39
