Rectangles that are 5×20, 6×12, or 8×8 will satisfy your criteria. The sum of the areas of those is 236 units².
_____
20×5 and 12×6 rectangles are also "cool", but their areas are not different from those already counted.
Answer with Step-by-step explanation:
Since we have given that
a + b = c
and a|c
i.e. a divides c.
We need to prove that a|b.
⇒ a = mb for some integer m
Since a|c,
So, mathematically, it is expressed as
c= ka
Now, we put the above value in a + b = c.
So, it becomes,
a=mb, here, m = k-1
Hence, proved.
Uh add and than subtract you will get the answer jsjskskskskskeke.
Choice B would be the correct answer. I hope that helps! :D
