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!

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

6 on both sides and twelve on the top and the bottom
