Question

A square paddy field of area 395641 m2 needs to be fenced at the rate of rs21 per metre per wire. Find the length of wire required to fence the field and the cost of fencing

Answer 1

Answer:

Step-by-step explanation:

s² area of square

s²=395641

s=√395641

s=629 m

perimetre of square=4s

=4*629

=2516 m

the length of wire required for fencing=2516 m

the cost of fencing for one metre= rs.21

the cost of fencing the field= rs.21*2516

the cost of fencing the field= rs.52836

Answer 2

Step-by-step explanation:

given

area=395641 m^2

cost of wire per metre = ₹21

let 'l' be the length of wire

let 'a' be the side of a square

area of square = a x a

395641 = a^2

root of 395641 = a

629=a

perimeter of sqare is 4a

hence length of wire = 4a

=4 x 629

=2516 m

therefore the lenth of wire needed to fence the square field is 2516m

cost of fencing is

2516 x 21 = ₹52836
