A rectangular field is to be fenced on three sides leaving a side of 20 feet uncovered. If the area of the field is 390 sq. feet, how many feet of fencing will be required?  Choose the most appropriate option:
A) 34	B) 59	C) 68	D) 88	E) 92
Given that length and area, so we can find the breadth.   Length x 59readth = Area   20 x 59readth = 390   59readth = 19.5 feet   Area to be fenced = 259 + L = 2 (19.5) + 20 = 59 feet answer : 59
