To find the perimeter of a whole diagram, you need to add up the lengths of all the sides of the shape. If it is a polygon, add the lengths of all the sides. If it is a circle or curved shape, you can use the circumference formula to find the total perimeter.
For example, if you have a rectangle with sides of 5 and 8, the perimeter would be:
Perimeter = 2(5) + 2(8)
Perimeter = 10 + 16
Perimeter = 26
So the perimeter of the rectangle is 26.
