A picture 10 feet long is to be centered on a wall that is 14. feet long. How much space is there from
the edge of the wall to the picture?
we have that
the center of the wall is 7 ft from the edge
the center of the picture is 5 ft from the edge
therefore
the distance from the edge of the wall to the picture is
5-(7-5)=5-2=3 ft
the answer is 3 ft
