Answer 1

looks good to me
we can check it with numbers if you like

Answer 2

C is correct


A = L*W

2*A = 2*(L*W)

2*A = L*(2*W)

So this shows that if the width (W) and area (A) are doubled to get 2*W and 2*A respectively, then the length must be held the same

Answer 3

@jim_thompson5910 Thank you , may you check this one.
I got C. as well.

Answer 4

yes the doubling and the halving cancel each other in a way

so you're left with the same area
