The length of a rectangular plot is 20 metres more than its breadth. If the cost of fencing the plot @ 26.50 per metre is Rs. 5300, what is the length of the plot in metres?

A. 40 B. 50
C. 120 D. Data inadequate
E. None of these    

Answer: Option E

Explanation:

 

Let breadth = x metres.

Then, length = (x + 20) metres.

 

Perimeter = 5300 m = 200 m.
26.50

 

 2[(x + 20) + x] = 200

 2x + 20 = 100

 2x = 80

 x = 40.

Hence, length = x + 20 = 60 m.
