Each of the small boxes in the figure below is a square and the area of the figure is 52 square units. How many units are there in the outer perimeter of the figure?
There is a drawing.
first row has 1 small box
2nd row has 3 small boxes
3rd row has 4 small boxes
4th row has 3 boxes
5th row has 1 box
sorry, don't know how to draw the box on this site.
I would appreciate anyone's help.
