Triangular Flower Garden

      The Smith family lives in Rochester, New York. They love the environment outside the big city because they all love to spend most of their free time around their 20 acres land. 

     Louise loves to spend her summer landscaping their yard. Her flower garden is formed like a triangle with the sides 3x + 5, 6x - 7 and 5x + 2. What is the perimeter of Louise's flower garden?
