How many different triangles with a perimeter of 15cm can be constructed that have integral multiple of sides? Star mark questn

• 7 triangles...
  1. (7,4,4)
  2. (7,5,3)
  3. (7,6,2)
  4. (7,7,1)

  7. (5,5,5)

• answer:3
  solution:
  the term "multiple integral" means that suppose sides of triangles are X>=Y>=Z then Y should b devisible by X and Z should b devisible by X&Y.. s
  
  so there are only 3 pairs
  1,7,7
  3,6,6
  5,5,5
  such that perimeter is 15.
  
  so answer is 3
