20x2= 40 just like 20+20=40
That would be A.
This is called the Contrapositive :-
If A implies B then Not B implies Not A.
Hello!
First you have to find the area of the bigger square
When it goes from the center to a corner you multiply the value by 2 to find one side
9 * 2 =18
Now you find the area
18 * 18 = 324
Now we find the area of the smaller region
4 * 2 = 8
Find the area
8 * 8 = 64
Now we subtract these
324 - 64 = 260
The answer is 260
Hope this helps!
