PLZZZ HELLPPP SOON REWARD BRRIANIESTTT

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!
