     A person has 56 inches of picture frame molding to frame a square picture. What are the constraints on the length in inches of a side s of the square in order to have enough frame molding? 
  
  Solution
The total length of frame molding = 56 inches
The total lenght of all sides of picture fram shall be less than the molding length
Let the lenght of side of equare be x
So, 4*x <= 56
x <= 14 inches this is the constraint on the length of picture fram
