A rectangular football field is fenced on all four sides. The length of the football field is twice the length of its breadth. The cost of fencing the field was $300. The football management has decided to change the dimensions of field by increasing the breadth by 5% of its original value and reducing the length by 20% of its original value and fence the field again.. What will be the cost of the new fencing?  Choose the most appropriate option
A) $360
B) $265
C) $425
D) $405
E) $415
Let's take x to be the breadth. Then the length of the football field is 2x.   The perimeter of the old football field is x + 2x + x + 2x = 6x.   Now, for the new football field:   The new breadth = 1.05 times old breadth = 1.05x   The new length is 0.8 times old length = (.8)2x = 1.6x   So the new perimeter is 1.6x + 1.6x + 1.05x + 1.05x =5.3x.   for old perimeter rate is $300   For new perimeter  1.6  + 1.6  + 1.05  + 1.05=

5.3x.   for old perimeter rate is $300   For new perimeter= (300 * 5.3)/6=

<output>265</output>
265   Ans - $265
