Answer 2

Area of square field=1764sq.m

we know that,

area of square =(side)^2
1764=(side)^2

[by taking square root to both sides)

side of square field is 42m.

Perimeter of square =4(side)
=4(42)=168m.

Therefore,
The perimeter of square field is 168m.

The cost of build a wall
=168×250
=₹42,000

Therefore,
The cost to build a wall around the square field is ₹42,000 .
