A3” x 5” photo is enlarged so that the length of the new photo is 7 inches. find the width of the new photo.. a. 4.20 inches. c. 5.25 inches. b. 6.75 inches. d. 7.20 inches.

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.
