Question

a path 4 metre wide runs along inside a square park of side 90 find area of path and the cost of cementing it at the rate of rupees 150 per metre square​

Answer 1

Answer:

Hey there, the area of the path is 1504 m² and the cost of cementing the path is ₹2,25,600.

Step-by-step explanation:

Given inner side of square park, s=90 m

Area of inner square =(90m)²=8100m²

2

width of path,w= 4m

Outer side of square = 90+4+4 m= 98m

Area of outer square =(98m)²= 9604 m²

2

Therefore, area of the path=

9604m²- 8100m²

= 1504 m²

And, cost of cementing the path on ₹150 per m²= ₹(1504×150) = ₹ 2,25,600.
