You can put this solution on YOUR website!
For your example, it's adding up all the numbers you've shown. Since there are 3 you are finding the perimeter of a triangle.

Answer is 12 cm.

For a rectangle you would add up four sides where Perimeter P= 2(w+l) where w is the width and l is the length.
