Answer 1

The answer would be: option B!

To find the perimeter of a rectangle you must add each side together. If the width is 6 inches we can deduce that one other side is also 6 inches so you add the two sides and you get 12. You subtract this amount from the total perimeter 42-11=30. There are still two sides to find so we would divide 30 by two and we get our answer 15. The length is 15 inches!
