Question 1159270
The description unclear.  Just how is the border?  Outside of the canvas?  Is most of the canvas to be painted leaving the outer 8 inch width unpainted?  


-

The canvas is 8 foot by 10 foot, and WITH IT IS a border of 8 INCHES all the way around.  The border surrounds the canvas.


The outside dimensions of the border are then  {{{8+2(2/3)=9&1/3}}}  and {{{10+2(2/3)=10+4/3=11&1/3}}}.


The perimeter of this border is  {{{2(9&1/3+11&1/3)}}}{{{feet}}}.
