If the sides of triangle ABC are 7 cm, 24 cm, and 25 cm, what is the perimeter of the triangle?
  • Step 1: Identify the lengths of the sides of triangle ABC. They are 7 cm, 24 cm, and 25 cm.
  • Step 2: Write down the formula for the perimeter of a triangle, which is the sum of the lengths of all its sides.
  • Step 3: Substitute the lengths of the sides into the formula: Perimeter = 7 cm + 24 cm + 25 cm.
  • Step 4: Add the numbers together: 7 + 24 = 31, then 31 + 25 = 56.
  • Step 5: State the final result: The perimeter of triangle ABC is 56 cm.
