Answer:

10.8 inches long

Explanation:

We can determine the width to length ration by dividing 10 inches by 12 inches:


=10/12=5/6

For every 5 inches wide the paper is 6 inches in length. If the picture is reduced to 9 inches in width, we can calculate the length by taking the inverse of 5/6 which is 6/5 and multiplying by 9 inches:


=(6/5)\cdot{9}=10.8

the paper is 10.8 inches long
