A zombie lives in a cemetery. The cemetery is 48 feet long and 36 feet wide. If the cemetery is a rectangle, what is its perimeter?
To find the perimeter of a rectangle, we add up all the sides.
The length of the cemetery is 48 feet, which means there are two sides that are 48 feet long.
The width of the cemetery is 36 feet, which means there are two sides that are 36 feet long.
So the perimeter is 48 + 48 + 36 + 36 = <<48+48+36+36=168>>168 feet. Answer: \boxed{168}.
