Calculating Total Fencing for a Garden with Walking Path

A rectangular garden measures 12 feet in length and 9 feet in width. A walking path that is 1 foot wide is to be built around the garden. What will be the total length of the fencing needed to enclose the garden along with the walking path?

To find the total length of fencing, calculate the new dimensions of the garden including the walking path, and then find the perimeter of the new rectangle.
