please help im so stuck

Answer:
Step-by-step explanation:
since its a square, the outsides are 6x6.
since the area of A is two times of B, we just have to guess the dimensions of the shorter side. The longer side is always going to be 6, it doesn't get cut there. so A is 6x4=24 and B is 6x2=12. 24 is twice 12. 2:1 ratio
Rect A
L=6
W=4
Rect B
L=6
W=2
