----------------------------------------------------------------------------------------
Given information
----------------------------------------------------------------------------------------
Side length of a square = 2x² + 1
Perimeter of the square = 4(2x² + 1)

----------------------------------------------------------------------------------------
If x = 3.5, find perimeter
----------------------------------------------------------------------------------------
Perimeter of the square = 4(2(3.5)² +1)
Perimeter of the square = 4(2(12.25) +1)
Perimeter of the square = 4(24.5 +1)
Perimeter of the square = 4(25.5)
Perimeter of the square = 102 inches

----------------------------------------------------------------------------------------
Answer: Margot will need 102 inches of the ribbon.
