Question: In triangle ABC, if the lengths of the sides are a = 5, b = 12, and c = 13, what is the perimeter of the triangle?

Options:

Correct Answer: 25

Solution:

The perimeter of a triangle is the sum of its sides. Therefore, perimeter = a + b + c = 5 + 12 + 13 = 30.

In triangle ABC, if the lengths of the sides are a = 5, b = 12, and c = 13, what is the perimeter of the triangle?

Correct Answer: 30

Step 1: Identify the lengths of the sides of the triangle. Here, a = 5, b = 12, and c = 13.
Step 2: Understand that the perimeter of a triangle is found by adding the lengths of all its sides together.
Step 3: Write the formula for the perimeter: perimeter = a + b + c.
Step 4: Substitute the values of a, b, and c into the formula: perimeter = 5 + 12 + 13.
Step 5: Perform the addition: 5 + 12 = 17, then 17 + 13 = 30.
Step 6: Conclude that the perimeter of triangle ABC is 30.
