Question

the total cost of cultivating a rectangular field at 15 per m is rs.18330 .if the breath of the field is 26m ,Find the cost of fencing the field at Rs. 20 per metre.

Answer 1

Hi,

Area of the field =(18330)/(15) =1222m²

Area of the field =1222m²

Lenght * breadth =1222m²

26*lenght =1222m²

Lenght =1222/26

Lenght of the field =47m

Then the perimeter of the field will be

2(47+26)

=2*73

=146

Then the cost of fencing the rectangle =20*146

Cost of fencing =Rs 2920


I hope this will help you

Answer 2

If cost of cultivating field is Rs 15 per m sq that is Rs 18330.
Then area will be 18330/15
So, area of field is 1222m sq
Length of the field is 1222/26
Lenght is 47m.
Perimeter of rectangle is 2(l+b).
2(26+47) : 146
Cost of fencing per m sq is Rs 20.
So the answer for question will be 20× 146.
That is Rs 2920.
