Question 1055987
Draw a picture of this.  Let the p be the perimeter.  That is the length of the molding needed.  The two-inch mat around the "picture" does not matter in this exercise.  Or, maybe it does matter.  You would maybe need to cut off a right triangle on both sides of each of the four pieces.  Yes.  That's it.


Look at the outside perimeter.


{{{2(11+2*2)+2(14+2*2)=outerPerimeter}}}
p for outer perimeter,
{{{p=2*15+2*18}}}
{{{p=2(15+18)}}}
{{{p=66}}}--------------this is how much molding.
