perimeter of the rectangle field = 1980/23
=110
perimeter of the field = 2 ( l + b )
110 = 2 ( l + 23 )
110/2 = l + 23
55 = l + 23
l = 55 - 23
length = 32
=110
perimeter of the field = 2 ( l + b )
110 = 2 ( l + 23 )
110/2 = l + 23
55 = l + 23
l = 55 - 23
length = 32

rate of fencing=18 then total cost =1980 area =1980/18=110m2. area= l×b then 110= l×23 then l = 110/23=4.78(approx)
