Question

The total cost of fencing a square park at Rs. 20 per metre is Rs. 2880. Find the side of the square park.​

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

Answer 2

Answer:

20,000 is the side of the square park.
