You can put this solution on YOUR website!
The area of the picture (without the frame) is 5*7 = 35 square inches

Now add 1 inch to each side (this will mean you're effectively adding 1+1 = 2 inches to each dimension): 5+2 = 7 and 7+2 = 9

So the overall dimensions of the picture and the frame combined are 7" by 9"

The area of this is 7*9 = 63 square inches.

-------------------------------------------------------

The area of the frame alone is then the difference between the area of the picture+frame and the picture alone (a drawing may help see this)

So the area of the frame is then:

(Area of picture+frame) - (Area of picture only) = 63 - 35 = 28

So the area of the frame only is 28 square inches.

So if you have a thin strip of material that is 1 inch in width and 28 inches in length, then this would be a starting point for the frame.
