Emily made a sketch of an octogonal window on a 27-inch square piece of paper. first she cut four identical isosceles triangles from the corners of the paper. then she cut a square from the center of the octagon. each leg of a cut off triangle in 1/3 the length of the paper. the dude length of the cut out square is also 1/3 the length of the paper. what’s the area of the sketch after she removed he triangles and the square?
