I have problems compiling this and i get several errors
including 2143, 2059, 2228, 2018,
please help

I'm guessing the syntax error is because one } is missing (at the very end of your program) and also one is turned backward (beginning your main-function).

float height = 0 .0;
float rollCoverage = 0 . 0;
float perimeter = 0 . 0;
float area = 0 . 0;
float rolls = 0 . 0;


Make sure the values say 0.0 without any blanks between numbers and decimal-points..
