A rectangular fence has a perimeter of 1080 feet. The length is 3 feet more than twice the width. I need to know the dimensions and how to figure it out.

  • Algebra -

    width: w
    length: 2w+3

    so 2w + 2(2w+3) = 1080

    solve

    I am sure you can take it from here.

    how do you do two step equations

  • Algebra -

    don't know what you mean by 'two step' equations but here is how I would continue

    2w + 2(2w+3) = 1080
    2w + 4w + 6 = 1080
    6w = 1080 - 6
    6w = 1074
    w = 179

    then length = 2w + 3 = 2(179) + 3 = 361
