Question

rectangular lawn is to be surrounded externally by a path which is 3 m wide. I the one
are 35 m and 45 m, find the cost of constructing the path at the rate of 100 per m.​

Answer 1

Step-by-step explanation:

length of rectangular lawn= 35m

width of rectangular lawn= 45m

length of path= (35+3+3)=41m

width of path=(45+3+3)=51m

area of lawn= 35*45=1575m^2

area of path= (41*51)m^2-1575m^2

= 2091m^2-1575m^2

=516m^2

cost of 1m^2= 100

cost of 516m^2= 100*516= 51600
