Hi

each of the two longer sides of the triangle is three times as long as the shortest side

Let x, 3x and 3x represent the length of the sides

Question states***

  x + 3x + 3x = 84cm

solving for x

     7x = 84cm

      x = 12cm, the shortest side, the other two sides are 36cm and 36cm



CHECKING our Answer

  12cm + 36cm + 36cm = 84cm
