the perimeter is 48, the length is 2 times the with. what is the width and length. I got the answer but how do you figure it out, is it a formula?

  • math -

    What shape are you dealing with?
    A rectangle?

    If so, then perimeter = 2L + 2w

    let the width be W
    "the length is 2 times the with" ---> l = 2w

    so 2L + 2(2w) = 48
    6w = 48
    w = 8
    then l= 16

  • math -

    P = 4W + 2W
    48 = 6W
    8 = W
