Question

What is the perimeter of the rectangular field?
I. Area of the field is $72m^2$
II. Length and breadth are in the ratio of 2 : 1.

• A. The data in statement I alone is sufficient to answer the question.
• B. The data in statement II alone sufficient to answer the question.
• C. The data either in statement I alone or statement II alone are sufficient to answer the question
• D. The data given in both I and II together are not sufficient to answer the question
• E. The data in both the statement I and II together are necessary to answer the question

Answer 1

The correct option is E The data in both the statement I and II together are necessary to answer the question

From both equations, we get 1 = 12 and b = 6 so perimeter = 36
