280 feet.

Step-by-step explanation:

Chuck has 140 feet of fencing in which he wants to fence in two connecting, adjacent square pens with fencing between the two pens.

If the width of each pen is a feet, then (3a + 4a) = 7a will be the length of the fence.

So, 7a = 140

⇒ a = 20 feet

So, the length of the connecting adjacent pens will be twice the width of each pen.

If the width of the pens is 20 feet, then the length of the connected pens will be (20 * 2) = 40 feet. (Answer)
