Question

the cost of fencing rectangular at rupees 30 per metre is 2700 in the length of a field 24 M find its breadth

Answer 1

The cost of fencing rectangular field at Rs 30 per meter is Rs2700.
The area will be= total cost for fencing /cost per meter
=2700/30
=900m^2
Length=24m
Area=900m^2
Breadth=Area/length
=900/24
=37.5m

Answer 2

Length=24m
Total cost =RS 2700
Cost per month =RS 30
Let the breadth be x
ATQ,
Perimeter of rectangle = 2(l+b)
To find perimeter,
P= 2700/30=90m
Now,
2(l+b)= 90m
=2(24+x)= 90m
=48+2x= 90m
=2x=42m
Hence, x= 21m
Thus, breadth of rectangle=21m
