Answer:
B. 8 cm.
Step-by-step explanation:
The area of a rectangle is the length*width.
The area of the larger rectangle is 4*12=48.
The area of the smaller rectangle is 3*x=3x.
If the larger rectangle's area is twice that of the smaller rectangle, then we can say 48=2*3x.
Let's solve for x
48=2*3x
48=6x
x=8
