The answer is 73.5
To make it a lot easier split the shapes into a rectangle and triangle. 
The rectangle is a tad easier because the measurements are given here. 
5 x 12 = 60 (rectangle area)
To find the triangle find the base then height. The base is 3cm and the height is 9cm (shown above)
9 x 3 = 27 
Divide that by 2 because it's a triangle and you get 13.5. 
Add those two numbers and voila you have your answer of 73.5.
        
             
        
        
        
It might be nineteen because nineteen minus seven is twelve. twelve minus two is ten.
        
             
        
        
        
Triangles are the easiest shape to make a hexagon out of. You can do this by lining up 6 triangles where each base of the triangle lines up.
