Answer:
A= (0,0) and B = (6,3)
We can find the length AB with the following formula:

And replacing we got:

So then the length AB would be 
Step-by-step explanation:
For this case we have the following two points:
A= (0,0) and B = (6,3)
We can find the length AB with the following formula:

And replacing we got:

So then the length AB would be 
Answer:
area(rectangle) = Length * width
8w + 18 = 2 * w
8w + 18 = 2w
