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
