Question 867024: How do you find the perimeter of a rectangle with a hole in the middle? Do you still only add up all the outer sides OR do you also add the sides created in the middle of the shape that's been cut out?
For example: The big rectangle has 6cm as the height and 9cm as the base with a small rectangle cut out of the middle of the big rectangle.
Any help would be appreciated. Thanks

They are two separate perimeters. Each has its own value, or each is a separate number. The use of one of them or both of them depends on the application; otherwise, they are two separate numbers.
