Question

Find the cost of fencing a Square park of 120 m at the rate of rupees 30 per meter??

Answer 1

We have,
Length of fence covered = Perimeter of the square park
We know that,
Perimeter of square = 4 × Side of square park
= 4 × 120 m
= 480m
It is given that,
Cost of fencing of a square park = Rs. 30
Therefore,
Cost of fencing 1000 m of square park = 480x30
= Rs. 14,400

Answer 2

perimeter of square =4*side.
4*side=120÷4
=30rs.
hence the perimeter is 30 rs
