What is the perimeter of rectangle?
The perimeter of a rectangle is the total length of all the sides of the rectangle.
P = 2 (L + B)
P = perimeter of rectangle, L = Length of rectangle, B = Breadth of rectangle
Given length of garage door = 12 feet
Given breadth of garage door = 16 feet
P = 2 (L + B)
P = 2 ( 12 + 16)
P = 2 (28)
P = 56 feet
Hence, The total length of the banner should be 56 feet to cover the entire door.
