Length of a rectangular plot is 30 mtr more than its breadth. If the cost of fencin g the plot at 26.50 per meter is Rs. 5300, what is the length of the plot in mtr?
Choose the correct choice from the following answers
A) 46 m
B) 60 m
C) 65 m
D) 78 m
E) 80 m
Let breadth = x metres.   Then, length = (x + 30) metres.   Perimeter = 5300/26.5= 
<gadget id="calculator">5300/26.5</gadget>
<output>200</output>
200 m.   2[(x + 30) + x]= 200   2x + 30 = 100   2x = 70   x = 35.   Hence, length = x + 30 = 65 m   65 m
