Question

A rectangular grassy lawn measuring 30m by 28m is to be surrounded extremely by a path which is 2.5m wide. Find the cost of levelling the path at the rate of ₹4 per sq.m​

Answer 1

Answer:

Length of lawn =30m

Breadth of lawn =28m

Therefore,

Area of lawn (A1)=l×b=30×28=840m^2

Now,

Length of lawn including path =30+2.5+2.5=35m

Breadth of lawn including path =28+2.5+2.5=33m

Therefore,

Area of lawn including path (A2)=35×33=1155m^2

Therefore,

Area of path =A2−A1

=1155−840=315m^2

Cost of levelling =Rs.4 per square meter

Therefore,

Cost of levelling path =4×315=Rs.1260
