What is the perimeter of a triangle with sides measuring 5 cm, 12 cm, and 13 cm?

• A. 30 cm
• B. 28 cm
• C. 25 cm
• D. 22 cm

Answer: (A)

To find the perimeter of a triangle, you simply add the lengths of all its sides together. In this case, the lengths of the sides of the triangle are 5 cm, 12 cm, and 13 cm. Calculating the perimeter involves the following steps: 1. Add the first side (5 cm) to the second side (12 cm): 5 cm + 12 cm = 17 cm. 2. Then, add the result to the third side (13 cm): 17 cm + 13 cm = 30 cm. Therefore, the perimeter of the triangle is 30 cm. This is consistent with the information provided and confirms that 30 cm is indeed the correct answer.
