Question

What scale factor was applied to the first rectangle to get the resulting image? Enter your answer as a decimal in the box. A rectangle with a short side of 2.5. An arrow points to a smaller rectangle with a short side of .5

Answer 1

Answer:

0.2

Step-by-step explanation:

If the arrow points to the smaller rectangle this means the square reduced size

$sf=\frac{0.5}{2.5}$

$sf=0.2$

Another way to look at it is that the rectangle was reduced in a factor of 5 (1/0.2=5)

Answer 2

The rectangle shorts side became 5 times shorter than what it was originally.
all you have to do is 2.5/.5 and you get 5.
