Answer 2

Answer:

Area = 124 sq.m

Cost = Rs 8680

Step-by-step explanation:

Width of path = 1m

Side of square park = 30m

Side of square with path = 30+1+1 m

= 32m

Area of park with path = Side × Side

= 32×32 sq.m

= 1024 sq.m

Area of park = Side × Side

= 30×30 sq.m

= 900 sq.m

Area of path = Area of park with path- Area of park

= 1024-900 sq.m

= 124 sq.m

Cost of 1sq.m constructing = Rs 70

Total cost = Cost of 1 m constructing × Area of path

= 70 × 124

= Rs 8680
