1. length= 135m
breadth= 60m
perimeter = sum of all sides
= 135+135+60+60
=390m
cost of fencing
1m= rupees 60
390 m = 390×60
= rupees 23400
2. l:b=7:4
let l be 7x and b be 4x
then 7x+7x+4x+4x=440
on solving it x= 20
then l = 7x= 140 m
and b= 4x= 80m
breadth= 60m
perimeter = sum of all sides
= 135+135+60+60
=390m
cost of fencing
1m= rupees 60
390 m = 390×60

1.L=135m B=65m
l×b=)

8775m
cost of 1m=rs.60
cost of 8775m=60×8775=526500
2.7x×

11x=440

=40m
7x=7×40=280m
4x=4×40=160m
l×b=)
8775m
cost of 1m=rs.60
cost of 8775m=60×8775=526500
