scale factor is 1:3.5

Step-by-step explanation:

56/16 = 3.5

The scale factor expressed as a fraction is 4/5

Since the right triangle on the right is a scaled copy of the right triangle on the left, then the ratio of their similar sides is equal to the scale factor.

This is expressed as:

Taking the ratio of the fractions

\frac{20}{25} = \frac{4}{5}

25

Similarly for \frac{12}{15}

15

12

\frac{12}{15} =\frac{4}{5}

15

12

=

5
