25. Matt purchased a 60-foot-long roll of chain-link fence. He used the entire roll of fence to construct a recta agular pen for his dog. Given that the pen is 12 feet wide, what is its length, in feet? A. 5 B. 18 C. 24 D. 36 E. 48

## Step 1The problem involves the use of the Perimeter formula for a rectangle. The Perimeter of a rectangle is given by the formula:### where is the Perimeter, is the length, and is the width of the rectangle.## Step 2In this problem, Matt used the entire 60-foot-long roll of fence to construct a rectangular pen. This means that the Perimeter of the rectangle is 60 feet.## Step 3The width of the rectangle is given as 12 feet. We can substitute these values into the Perimeter formula to find the length of the rectangle.## Step 4Substituting the given values into the formula, we get:### ## Step 5Solving this equation for , we find that the length of the rectangle is 36 feet.
