1 acre equals 4840 square yards. 
The minimum perimeter to  enclose 1 acre would be a square with sides of {{{sqrt(4840)}}} anf then the perimeter would be 
{{{P=4s=4*sqrt(4840)=278.2}}}yds.={{{834.6}}} ft
For 2 acres, 
{{{A=9680}}}
{{{s=sqrt(9680)}}}
{{{P=4s=4*sqrt(9680)=
393.5}}}yds.={{{1180.6}}} ft
