A company makes picture frames for different sized pictures. A customer has several rectangular-shaped photographs that he wants to be framed. All of the photographs measure 10½ inches for width but vary in length. The manager at the frame shop knows she can use the formula for perimeter, P = 2l + 2w, to determine the amount of wood that she’ll need for each photograph.

One of the photos is 20¾ inches long. How much wood is needed for the frame? The type you answer as a decimal, not a fraction.
