How do you solve this? A farmer has 680 feet of fencing....

[peaceful4]

A farmer has 680 feet of fencing to enclose the pasture shown in the figure below. Because a river runs along one side, fencing will be needed on only three sides. Find the dimensions of the pasture if its length is double its width.

Choose the correct answer from the following.

Length: 170 ft; width: 340 ft

Length: 342 ft; width: 171 ft

Length: 340 ft; width: 170 ft

Once again, name some stuff and set it up. Draw a picture. No need to include any horses.

Rather than just doing a copy-n-paste from your online assessment (and omitting necessary information), please show what you have tried and specify where you are stuck. (Most tutors will not complete your assessment for you, is why I suggest this.)

Thank you.
