The area of the rectangular field is 340 m
the bredth is 17 m
hence the length will be 340/17=20
Thus the perimeter will be 2(l+b)
which is 74m.
the cost of fencing will be perimeter * cost of fencing
=74*5.70
=421.8 rs
the bredth is 17 m
hence the length will be 340/17=20
Thus the perimeter will be 2(l+b)
which is 74m.
the cost of fencing will be perimeter * cost of fencing
=74*5.70
=421.8 rs

Area of rectangular plot = 340 metres
Breadth = 17m
Formula of area of rectangle = Length* Breadth
340= Length *17
340/17 = Length
Therefore, Length = 20m
Perimeter of the rectangle = 2*(length+breadth)
Perimeter= 2* (20+17)= 2*37 = 74m
Rate of fencing per metre= 5.70 rupees/ metre
Thus, cost = perimeter* Rate/metre
Cost = 74m * 5.70 rupees/ metre = Rs. 421.8
Therefore, the total cost for fencing the plot is Rs. 421.8
Breadth = 17m
Formula of area of rectangle = Length* Breadth
340= Length *17
340/17 = Length
Therefore, Length = 20m
Perimeter of the rectangle = 2*(length+breadth)
Perimeter= 2* (20+17)= 2*37 = 74m
Rate of fencing per metre= 5.70 rupees/ metre
Thus, cost = perimeter* Rate/metre
Cost = 74m * 5.70 rupees/ metre = Rs. 421.8
Therefore, the total cost for fencing the plot is Rs. 421.8
