The scale factor is

A. 0.8
B. 1.25
C. 4
D. 5

Answer 1

The answer is B because 4 x 1.25 is 5

Answer 2

The first pentagon is dilated to form second pentagon as shown in the given figure.

We have to find the scale factor.

A scale factor is a number which scales, or multiplies, some quantity. The ratio of any two corresponding lengths in two similar geometric figures is also called a scale factor.

Therefore, Scale factor =
`(5)/(4)`

= 1.25

And we can observe,,
`4 * 1.25 = 5`

Therefore, 5 is the scale factor.
