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.
