Consuelo has just had a roll of film developed. She particularly likes a family picture of herself, her husband, and her 2 children. She decides to take this photo, which is 5 inches long and 3 inches high, to her friend's photo shop to have it enlarged. She tells her friend that she wants the enlargement to be similar to the photo she already has but with a height of 12 inches. Her friends says that she will have the enlargement ready in 3 days. What is the length of the new enlargement?
