To promote her school's annual Science Fair, Brandon makes a small kite and a large kite for a classroom display. The kites look like the one in the diagram below. For his small kite Brandon draws the kite on a one-inch grid. For the large kite he doubles both the height and width of the entire grid. The large kite is covered with blue paper. The paper is cut from a rectangular piece that just covers the entire grid. How many square inches of waste material are cut off from the four corners?
