A patio in the shape of a rectangle, is fenced on all sides with 134 feet of fencing. The patio is 5 feet less wide than it is long. What information can be used to solve the problem? Since the geometric formula for rectangle to determine its perimeter is:

P = 2l + 2w

The given values fit the given formula

The given values are 134

Let L = 5 - w

Solution:

P = 2l + 2w

134 = 2 (5-w) + 2w 134 = 10-2w + 2w 134 - 10 = 4w 124 = 4w

31 = w

26 = l
