Answer:
I think your answer would be the first one
Step-by-step explanation:
It kind of tells you
if you increase each side, which is 12, by x, you are adding x to each side.
the way i think they want you to put it into A=l*w
area =256
256=l*w
the sides are 12, but added by x
256=12+x^12+x
also written as
256=(12+x)(12+x)
hope this helps!
