                  10                     10

                              7

10 plus 10 is 20

34-20 is 14

14  divided by 2 is 7

Answer:

7 inches

Explanation:

Assuming that the photograph takes a rectangular shape, we are given the length, which is 10 inches. The formula for calculating perimeter is l + l + w + w. So, we know that two sides, which are the opposite sides, are congruent and that two sides of this photograph are 10 inches. Now, we have accounted for 20 of the total 34 inches and only need to solve for the remaining 14 inches. Since the sides will be congruent, we simply half 14 and find that the width is 7 inches.
