Answer 1

Answer:

Step-by-step explanation:

Breadth of lawn :- 60m

Length of lawn :- 80m

Breadth of swimming pool :- 6m

Length of swimming pool:- 20m

Therefore, the area of remaining part of the field

Area of the lawn - Area of swimming pool

= (L×B) - ( l×b)

= (60×80) - (20×6)

= 4800 - 120

= 4680 sq m.

Cost for planting grass / m square :- ₹ 30

= 4860 ×30

= ₹ 140,400 .
