This is not much of a question, because it doesn't take into account the width of the wood trim.

So you are asked to find the perimeter of the window, ignoring the width of the trim.

P = Perimeter = 2L + 2W.

Here, P = 2 (9 1/3 feet) + 2 (6 3/4 feet) = 2 (28/3 feet) + 2 (27/4 feet)

So P = 2[28/3 + 27/4] feet. LCD is 3*4 = 12.

Thus, P = 2 [ 28/3 + 27/4 ] feet. Can you finish? Add together the fractions 28/3 and 27/4.
