Question

a path 5m wide runs along inside a square park of side 100m. find the area of the path. also find the cost of cementing it at the rate of rupees 250 per 10m2

Answer 1

side of square park=100m
side of square park=100m

area of park/square=side X side
=100 X 100
=1000m sq
area of wide path I=100-5-5= 110
ii=100-5-5= 110
area of path I and II=110x110=1100

area of square path= 1000-1100=100m sq ans

cost of cementing it at the rate of 250 per 10 m sq=250m sq X 10m= 2500m sq

= 2500m sq X 100m
= ₹250000m sq
