Question

A rectangular garden 100 m long and 90 m wide. A path 5 m wide is to be built inside and around it. Find the area of the path and cost of cementing the path at rate of Rs 100 per m2 .​

Answer 1

Answer:

here

area of rectangle=l×b

=100×90=900m2

width of outer path =5

or area of path =2w(l+b+2w)

=2×5(100+90+2×5)m2

10(100+90+10)m2

=10×200m2

=2000m2

now;cost of cementing the path=rs 100 per m2

total cost=2000×100

=rs.200000
