Question

find the cost of building a fence around a square field whose area is 9000m if the rate of fencing is rupees 35 per metre

Answer 1

if 9000 is perimeter

perimeter of building=9000m

rate of fencing=9000*35

=315000rs

if 9000 id area

area of square building=9000m2

side*side=9000

side=94.86

perimeter=4*side

=4*94.868329805

=379.47331922

cost=(35)*379.47331922

=13281.566172

Answer 2

area= 9000m^2
side=
$\sqrt{9000}$
=94.86m


perimeter= 4×side
=4×94.87
=664.02m

cost= 664.02×35
= Rs23240.7
