A and c are the correct answers
The answer is 0.305. All you have to do is move the decimal place three times to the left.
2
Length x width= area
3/4 x blank= 3/2
So then you can divide area by the given length
3/2 divided by 3/4= 2
And to check your answer you would put 2 in as your width
3/4 x 2= 6/4. And 6/4 reduces to 3/2
