Question 96

A photographer uses a computer program to enlarge a photograph. What is the scale according to which the width has enlarged?

Answer 1

By the given graph, we have width before editing = 2 units
Width after editing = 4 units
We know that, $Scale=\frac{Sizebeforeediting}{Sizeafterediting}\therefore Scale=\frac{2}{4}=\frac{1}{2}=1:2$
Hence, scale used to enlarge the photograph is 1 : 2.
