Question

3. The photo below is being enlarged to form

a 16-by 20- inch print. What is the scale
factor being used to enlarge it?
4 in
5 in

Answer 1

4 in

Explanation:

Given the following data;

Length = 16 in

Width = 20 in

To find the scale factor;

Scale = 16:20

Dividing by 4, we have;

Scale = 4:5

Therefore, the scale factor is 4 in.

Scale = scale factor * ratio

Scale = 4 * (4:5)

Scale = 16:20
