=4n - 1
Since the sequence is add 4 and 3-4 = -1
20 x 4n = 80-1 = 79
As long as you keep the signs with the numbers the order doesn't matter. The cumulative property says that you can flip the numbers in any order and it will equal the same amount.

Answer:
9 times
Step-by-step explanation:
The best way to go about this is to give actual figures
Let us consider rectangular shape
Let us have a rectangle with dimensions 6 m by 12 m
The area will be 6 * 12 = 72 m^2
The shape having a similar dimension would have dimensions 12m by 36 m
So its area will be ;
18 * 36 = 648 m^2
So we finally proceed to make a division
Mathematically, that will be 648/72 = 9
So the area will be in the ratio of 1 to 9
