Question

find the cost of fencing a square plot of area 65536 square metres at the rate of rupees 75 per metre​

Answer 1

to find the cost per we have to find the perimeter of the land

area = a×a

65536= a×a

256×256 = 65536

so each side = 256m

perimeter of square is 4×a

= 4*256

=1024

perimeter= 1024m

cost = perimeter* cost per m

cost = 1024*75

=76800rs

cost = rs 76800
