As far as the old dimensions of the photo are concerned, Width of the photo = 3" Length of the photo = 5" New length of the photo = 7 inches Let us assume the new width of the photo = x inches Then 3/5 = x/7 5x = 7 * 3 5x = 21 x = 21/5 = 4.20 inches So the correct option among all the options that are given in the question is the first option. I hope that the answer has come to your help.
