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 $360. The football management has decided to change the dimensions of field by decreasing the breadth by 50% of its original value and increasing the length by 25% of its original value and fence the field again.. What will be the cost of the new fencing?  Options.
A) $360	B) $180	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 = 0.5 times old breadth = 0.5x   The new length is 1.25 times old length = (1.25)2x = 2.5x   So the new perimeter is 0.5x + 2.5x + 0.5x + 2.5x = 6x.   The new perimeter is the same as the older perimeter! So presumably the cost is the same at $360.   $360ns - $360 0.5  + 2.5  + 0.5  + 2.5=

6x.   The new perimeter is the same as the older perimeter! So presumably the cost is the same at $360.   $360ns - $360
