Length of lawn =30m Breadth of lawn =28m Therefore, Area of lawn (A1)=l×b=30×28=840m2 Now, Length of lawn including path =30+2+2=34m Breadth of lawn including path =28+2+2=32m Therefore, Area of lawn including path (A2)=34×32=1088m2 Therefore, Area of path =A2−A1=1088−840=248m2 Cost of levelling =Rs.5 per square meter Therefore, Cost of levelling path =5×248=Rs.1240
