Write expression where the solution is 19

Some examples, depending on how complex the expression is, are:
25-6
2(1+6)+5
4*4+3
0+19
(330-292)/2
1+2+3+4+1+2+3

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
