38 ft

#### Work Step by Step

To find how much fencing is needed to surround the walkway, calculate the perimeter of the walkway. Since 2 feet are added to each side of the garden to create the walkway, add 4 to the dimensions of the garden to find the dimensions of the walkway. base(b)$=5+4=9$ height(h)$=6+4=10$ Use the formula for perimeter and substitute. $P=2b+2h=2(9)+2(10)=18+20=38$
