A farmer has 100 feet of fencing to create a rectangular pen for his sheep. If the length of the pen is represented by x, write an inequality for the perimeter and graph it. What are the possible dimensions?

• 0 < x ≤ 50, 0 < w ≤ 50 - x

• 0 < x < 50, 0 < w < 50 - x

• 0 < x ≤ 100, 0 < w ≤ 100 - x

• 0 < x < 100, 0 < w < 100 - x
