Rate=Rs.5/m^2
and Cost=Rs.720
So,Area=720/5=144m^2
So,side of field=root 144=12m
so,perimeter of field=12×4=48m
Therefore,perimeter of triangle=48m
So,Each side=48/3m=16m
So,its area=root 3/4a^2=8root3 m
and Cost=Rs.720
So,Area=720/5=144m^2
So,side of field=root 144=12m
so,perimeter of field=12×4=48m
Therefore,perimeter of triangle=48m
So,Each side=48/3m=16m
So,its area=root 3/4a^2=8root3 m
