Let length =4x and breadth =3x
Now , 15.25 is the cost of fencing = 1m
2135 is the cost of fencing = 1/15.25×2135 m
= 140m
Now perimeter is 2(l+b) =140m
2(4x+3x) =140m
14x=140
x=140/14=10 m
Now , length of the side is 4×10= 40m
Now , 15.25 is the cost of fencing = 1m
2135 is the cost of fencing = 1/15.25×2135 m
= 140m
Now perimeter is 2(l+b) =140m
2(4x+3x) =140m
14x=140
x=140/14=10 m
Now , length of the side is 4×10= 40m
