Questions & Step-by-Step Solutions

What is the perimeter of a triangle with sides measuring 5 cm, 12 cm, and 13 cm?
  • Step 1: Identify the lengths of the sides of the triangle. They are 5 cm, 12 cm, and 13 cm.
  • Step 2: Add the lengths of all three sides together. Start with 5 cm + 12 cm.
  • Step 3: Calculate 5 cm + 12 cm, which equals 17 cm.
  • Step 4: Now add the result (17 cm) to the length of the third side (13 cm).
  • Step 5: Calculate 17 cm + 13 cm, which equals 30 cm.
  • Step 6: The total you calculated (30 cm) is the perimeter of the triangle.
