your answer
length = 7x
breadth = 4x
cost of fencing at rs.25 / m = 3300
at rs 1 m = 3300 / 25
= 132
as cost of fencing = perimeter
perimeter = 2 ( l + b )
2 ( 7x + 4x ) = 132
2 ( 11x) = 132
22x = 132
x = 132 /22
x = 6
length = 6 ×7 = 42 m
breadrb = 4×6 = 24 m
your answer
length = 7x
breadth = 4x
cost of fencing at rs.25 / m = 3300
at rs 1 m = 3300 / 25
= 132
as cost of fencing = perimeter
perimeter = 2 ( l + b )
2 ( 7x + 4x ) = 132
2 ( 11x) = 132
22x = 132
x = 132 /22
x = 6
length = 6 ×7 = 42 m
breadrb = 4×6 = 24 m

Answer:
Step-by-step explanation:
Let the length be 7x and breadth be 4x
2(7x+4x)25 = 3300
50 × 11x = 3300
11x = 3300÷50
11x = 66
x = 66÷11
x = 6
So length is 7×6=42cm and breadth is 4×6=24 cm.
