Answer:

  • 51 feet

------------------------

Let the length be l and width be w.

The ratio of length to width in a rectangle is 3 to 1:

  • l/w = 3/1 ⇒ l = 3w

The perimeter of the rectangle is 136 ft:

  • P = 2(l + w)
  • 136 = 2(3w + w)
  • 68 = 4w
  • w = 68/4
  • w = 17

The length is:

  • l = 3*17
  • l = 51 ft

The length of the rectangle 51 feet.
