Question

12. A rectangular lawn measuring 25 m by 16 mis to
be surrounded externally by a path which is 3 m
wide. Calculate the cost of levelling it at 3.50
per m2​

Answer 1

Step-by-step explanation:

length of the lawn=25m

breadth of the lawn=16m

area of the lawn(A1)=l x b = 25 x 16 = 400msquare

now,

length of lawn including path = 25+3+3

=31m

breadth of lawn including path = 16+3+3

=22m

area of lawn including path (A2)= l x b = 31 x 22

=682m^2

therefore area of the path = A2-A1 = 682-400

=282m^2

cost of levelling = RS. 3.50

therefore levelling the path = 3.50 x 282= Rs.
