The perimeter of a rectangle is 90 meters. The length is 9 meters more than twice the width. Find the dimensions.

I need the length and the width.

Thanks!

  • Algebra -

    width = w
    length = (9+2w)
    90 = 2 (w + (9+2w) )
    45 = 3 w + 9
    36 = 3w
    onward :)

    ah, 2x + (4x+18) = 90
    x = 12
