I counted all the the squares around the outside because I wanted to find the perimeter.
e.g along the top is 6 units square. So after that I was up to the area. With the area I divided them up into rectangles so it would be easier to work it out. On the corner the square is 2 times 2 and that is 4 then on the next square 4 times 4 and that is 16, on the next square 3 times 1 and that is 3 and the last square is 1 times 1 is 1. So I added 4 pulse 16 pulse 3 pulse 1 and that equals 24 units square and that is the area that is covered.
