a rectangular swimming pool has dimensions 45 metre by 20 metre concrete path of 3.5 m width is laid around it .Find the cost of laying the path at a rate ₹25 per m2​

Answer 1

Rs. 5993.75

Step-by-step explanation:

The computation of the cost of laying the path is given below:

= {area of(pool +path)- area of pool }

= ((45 + 3.5) × (20 + 3.5)) - (45 × 20)

= (48.5×23.5) - (45 × 20)

= 1139.75 - 900

= 239.75 square meters

Now the cost is

= 239.75 × 25

= Rs. 5993.75
