What is the area of this plot ?  

I. The perimeter of the plot is 208 metres. 

II. The length is more than the breadth by 4 metres.  

A) If the data in statement I alone are sufficient to answer the question B) If the data in statement II alone are sufficient answer the question
C) If the data either in I or II alone are sufficient to answer the question; D) If the data in both the statements together are needed.
 
Answer & Explanation Answer: D) If the data in both the statements together are needed.

Explanation:

The area of the plot can be determined from both I and II as follows .

Let the breadth of the plot be x metres Then, length = (x + 4) metres

Thus, perimeter s 208 metres  2(x + 4 + x) = 208 ,

                                             4x =200,  x = 50.

So. length =54 metres. breadth = 50 metres.

Area of the plot =  2700 m^2.

Hence, both I and II are required
