Answer:
6000
Step-by-step explanation:
Multiply .30 and 50 ... which is 15
You multiply the denominator on one side of the equation by the numerator and vice versa. So for example(S)I'm going to multiply 4 by nine and 3 times n. Then that comes out to 3n=36. After you multiply, you divide from both sides to get the variable by itself. So you would divide both sides by 3 and you're final answer would be n=13. Hope this helped!
The Answer is B because you add the length to the length and the width to the width
