2*(L+W) where L is the length and W is the width of the poster
The perimeter of a rectangular shape such as a poster is 2 x length + 2 x width. In this example the perimeter = (2 x 3) + (2 x 6) = 6 + 12 = 18 feet
It depends on a rectangular what.
Add up all of the lengths of the edges adjacent to one of the bases.
The standard perimeter of a rectangular building can be found by adding the lengths of all four sides. It is twice the sum of the length and width of the building.
Twice the (width plus length)

width*height*length=perimeter of a rectangular prism! :)

20ft is the perimeter.
The standard perimeter of a rectangular building can be found by adding the lengths of all four sides. It is twice the sum of the length and width of the building.
It is 2*(Length + Width).
Twice the (width plus length)
