Question 1020011: a rectangular field has to be fenced on three sides leaving a side of 20 feet uncovered. If the area of the field is 680 sq.feet, how many feet of fencing will be required Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! 20 ft of the rectangle needs no fence, but
the opposite side needs 20 ft.
Let = the length in ft of the adjacent
sides.
----------------
Let = length of fence needed ft
------------------- ft2 = area of field ft
-------------- ft ft
88 ft of fencing is needed
