Question

Find the cost of fencing a square field of area 2500 m^2, if each meter of wire costs ₹13.

Answer 1

Answer:

Given :

Total cost of fencing =Rs. 10080

Cost of fencing per meter =20

So perimeter =

20

10080

=504 m

So length of square =

4

504

=126 m

width of pavement =3 m

Length of inner square =126−3=120 m

So, area of pavement =Area of Outer square − Area of inner square

=126×126−120×120

Area of pavement=1476 m

2

Cost of pavement =1476×50

∴ Cost of pavement=Rs. 73800
