A rectangular field is to be fenced on three sides leaving a side of 20m uncovered. If the area of the field is 680m2, how many metres of fencing will be required.
The length of one side is 20 m and the area is 680m2.
⇒ Length of another side =68020=34m
The length of fencing required for the three sides =34+34+20
Hence the required fence is 88m
