Length offence required = Perimeter of the square park
= 4 × Side
= 4 × 250 = 1000 m
Cost forfencing 1 m of square park = Rs 20
Cost forfencing 1000 m of square park = 1000 × 20
= Rs 20000
Length offence required = Perimeter of the square park
= 4 × Side
= 4 × 250 = 1000 m
Cost forfencing 1 m of square park = Rs 20
