Question

A square paddy field of area 395641 sq m needs to be fenced at the rate of Rs.21 per metre wire. Find the length of the wire required to fence the field and the cost of fencing

Answer 1

Solution:

area of square paddy = 395641 m sq.

Side = sq. root of 395641 = 629 m

length of wire to fence it = perimeter of square paddy = 4*629 = 2516 m

Cost of fencing per m = rs. 21

Cost of fencing square paddy = rs. 21*2516 = rs. 52836.
