The length of a rectangular garden is 8 feet less than its length. If the garden is fenced in with 72 feet of fencing, what are the dimensions of the garden?

mybe u want to say "the width of a rectangular garden ".

if right than width=8, length=x, the perimeter=72

the formula： 2（width+length）=perimeter

so x=28

the dimensions of the garden is 28 * 8 feet
