♥️let the length be 5x and breadth be x
given, breadth i.e. x is 60m
length or 5x = 5 × 60 = 300
perimeter = 2(l + b) = 2(60 + 300)
=2 × 360 = 720 m
cost of fencing = 40 × 720 = Rs. 28800

Let the l be 5x and b be 1x
A/q
breadth is 60m
=>b=1x=60m..........equation 1
x=60m
Now,
l=5x=5×60=300m
Perimeter of this rectangular field=2(l+b)
2(300+60)m
=2×360
=720m
Rate=Rs.45/m
Cost for fencing=45×720
=Rs.32,400
