A photo needs to be enlarged from an original with a length of 9 inches and a width of 7 inches to a size where the new width is 14 inches. What is the new length? What is the scale factor?

OpenStudy (campbell_st):

so the ratio of widths... original:enlargement 7 : 14 so its doubled... so double the length
