Question

rectangular grassy lawn measuring, 38 m by 25 m vas been surrounded externally by a
2.5-m-wide path. Calculate the cost of gavelling, the path at the rate of 120 per
​

Answer 1

Answer:

ANSWER

Length of lawn =30m

Breadth of lawn =28m

Therefore,

Area of lawn (A

1

)=l×b=30×28=840m

2

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 (A

2

)=34×32=1088m

2

Therefore,

Area of path =A

2

−A

1

=1088−840=248m

2

Cost of levelling =Rs.5 per square meter

Therefore,

Cost of levelling path =5×248=Rs.1240
