Length of a rectangular plot is 50 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?  Select.
A) 46 m  B) 60 m  C) 58 m  D) 75 m  E) 80 m
Let breadth = x metres.   Then, length = (x + 50) metres.   Perimeter = 5300/26.5= 
<gadget id="calculator">5300/26.5</gadget>
<output>200</output>
200 m.   2[(x + 50) + x]= 200   2x + 50 = 100   2x = 50   x = 25.   Hence, length = x + 50 = 75 m   75 m
