How to find perimeter of 2 triangles

To find the perimeter of a triangle, you need to add the lengths of all three sides.

1. Measure the lengths of the three sides of the first triangle (let's call them a, b, and c).

2. Add the three lengths together: Perimeter of Triangle 1 = a + b + c.

3. Repeat steps 1 and 2 for the second triangle.

4. Add the perimeters of the two triangles together to find the total perimeter.

Total Perimeter = Perimeter of Triangle 1 + Perimeter of Triangle 2.
