Answer:
Scale factor: 4:1
Ratio of perimeter: 4:1
Step-by-step explanation:
So basically, there is difference between the ratio of areas and the scale factor.
The area of a shape is equal to the scale factor squared.
We know that the ratio of the 2 areas is 16:1
So, the scale factor must be: ![\sqrt[2]{16}: \sqrt[2]{1}](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B16%7D%3A%20%5Csqrt%5B2%5D%7B1%7D)
,
Which is basically 4:1
Because the ratio of the scale factor is also equal to the ratio of the perimeter, the ratio of perimeters is also 4:1

Step-by-step explanation:
Jocab will take 4 more weeks to buy that MP3 player.
<u>Step-by-step explanation:</u>
Given:
Cost of MP3 player = $ 195
Earning per week = $ 225
Expenses per week = $ 180
To Find:
Weeks still required to save money for buying MP3 player.
Formula to be used:
Savings per week = Earning - Expenses
Solution:
Savings per week = Earning - Expenses
= $ 225 - $ 180 = $ 45
Already saved = $ 55
Need to save = $ 195 - $ 55 = $ 140
So for 4 weeks savings = $ 45 × 4 = $ 180
Thus Jocab will take 4 more weeks to buy that MP3 player.
