Question

2. A path 3 m wide runs around the in de of a square park of side 60 m. Find the
area of the path.Calculate the cost of cementing it at the rate of Rs. 20.50 per sq m.​

Answer 1

Step-by-step explanation:

area of the square = side× side

=60×60

=3600m²

area of square with path = side with path× side with path

= 60+6×60+6

= 66×66

= 4356m²

Area of path = area of square with path- area of square

= 4356-3600

= 756m²

cost of cementing the path

= area of path × cost per sq. m

= 756×20.50

= Rs. 15498
