A rectangular field is to be fenced on three sides leaving a side of 34 feet uncovered. If the area of the field is 782 sq. feet, how many feet of fencing will be required?
A) 91 ft B) 80 ft C) 86 ft D) None of these

• We are given with length and area, so we can find the breadth.
  as Length * Breadth = Area
  => 34 * Breadth = 782
  => Breadth = 23 feet
  
  Area to be fenced = 2B + L = 2*23 + 34
  = 80 feet

• Area=l*w
  Given that area=782ft
  And one uncovered length=34ft
  782=34*w
  W=782÷34
  =23*2
  =46+34=80

• area=l*b
  one length is given 34feet. hence, b=23 feet.
  perimeter of 3 sides 23+23+34= 80 feet
