Area of photo = 8*10 = 80 sq. in.
Area of border = 144 sq. in (given)
New area of photo along with the border = 80+144 = 224 sq. in.

Now we can find new lengths in equal integer increments of 8 and 10 (since answer choices are integers)

+6 works as (8+6)*(10+6) = 16*14 =224

Last step, since border is of equal width on either side of the length and width of the photo, then the width of the border is 6/2 = 3.
