  That's partly right. Study this web site to learn what a perimeter is. http://www.mathopenref.com/rectangleperimeter.html

  Yay! You've got it!!!! The perimeter of the photo is: (2 * 9) + (2 * 12 = 18 + 24 18 + 24 = 42 inches ________________________________ Now add 2 inches to each side. 4 + 9 = 13 4 + 12 = 16 (2 * 13) + (2 * 16) = 26 + 32 26 + 32 = 58 inches for the perimeter of the frame
