Wayne and Kim were digging in the sand at the beach . Wayne dug a hole that was 12 inches deep and Kim dug a hole that was 9 inches deeper than Wayne's
Well since Kim dug a hole bigger than 12 inches by 9 inches, all you would have to do is add 12 to 9 which equals 21 inches. For the picture, you could draw Kim's hole being equal to Wayne's hole plus 9. little stick figures or something :)
