Answer:
The scale factor James used to go from Rectangle N to Rectangle P is 3 or 3:1
Step-by-step explanation:
Given that Rectangle N has an area of 5 square units. That is An = 5
Rectangle P has an area of 45 square units. That is Ap = 45
 The scale factor James used to go from Rectangle N to Rectangle P will be in the form
An/Ap = N^2/P^2
Where N and P are the factors
(N/P)^2 = 5/45
N/P = sqrt root (1/9)
N/P = 1/3
Cross multiply
P = 3N
The scale factor James used to go from Rectangle N to Rectangle P is therefore equal to 3 or 3:1
