Finding the Perimeter of a Triangle in 3rd Grade

To find the perimeter of a triangle in 3rd grade, you need to know the lengths of its sides. The perimeter of a triangle is the sum of the lengths of its three sides. Here are a few examples to illustrate how to find the perimeter of a triangle:

Example 1: If the lengths of the sides of a triangle are 9, 9, and 11, you can find the perimeter by adding the lengths of the sides together: 9 + 9 + 11 = 29.

Example 2: If the lengths of the sides of a triangle are 3, 4, and 3, you can find the perimeter by adding the lengths of the sides together: 3 + 4 + 3 = 10.

Example 3: If the lengths of the sides of a triangle are 20, 30, and 30, you can find the perimeter by adding the lengths of the sides together: 20 + 30 + 30 = 80.

So, the perimeter of a triangle can be found by adding the lengths of its sides together.
