if you cut it, you would have a sqaure and a small rectangle, and just use a simple method for this, base times height, and for the sqaure it would be 12, and for the small rectangle all you need to do is subtract to find the side, such as seeing 4 for the side of the square the side, so it would be 3 and 1 which is 3 so 12+3 is 15 the area is 15.
