The length of a rectangle is 2 inches more than twice its width. If the perimeter of the rectangle is 34 inches, find the dimensions of the rectangle

  • math -

    call width w
    then length = (w+2)

    perimeter = 2 w + 2(w+2)

    I think you can get it from there

  • math -

    w = width
    l = length
    p = perimeter
    p = 2w + 2(2w + 2)
    34 = 2w + 4w + 4 - distributive property
    34 = 6w + 4
    30 = 6w - move the 4 to the other side
    30/6 = 6w/6
    5 = w

    to check that
    w + w + (2w + 2) + (2w + 2)
    5 + 5 + (2(5)+ 2) + (2(5)+ 2)
    10 + 12 + 12
    =34
