Draw a line on the hole which forms a square. The square lengths are 3 inches because 12-9 equals 3. 3^2= 9 which is the area of that square below the rectangle. Draw another line to separate the big rectangle into two rectangles. The smaller of these two new rectangles dimensions are 4 by 7 in. 7x4= 28 ft as the area of the smaller rectangle. The dimensions are the larger rectangle are 4 by 9 inch. The area of the larger rectangle is 36 inches.
36+28+9=73 in^2 as the total area.
4y-y is NOT equivalent to 4.
4 is multiplied by 'y', and then 'y' is subtracted from that equation. Even if y=1, your equation would look like 4x1-1=3.
Hope that made sense:)
