Answer:

The scale factor is 3

Explanation:

The area of rectangle N is 5 units

The area of rectangle P is 45 units

Distance is times the scale factor

Area is times the scale factor squared

Volume is the scale factor cubed

Area of rectangle N * scale factor squared = Area of rectangle P

5 * SF ^2 = 45

Divide each side by 5

5/5 * SF ^2 = 45/5

SF ^2 = 9

Now we need to take the square root of each side to find the scale factor

sqrt(SF ^2) = sqrt(9)

SF = 3
