Answer:
Step-by-step explanation:
Breadth of lawn :- 60m (B)
Length of lawn :- 80m (L)
Breadth of swimming pool :- 6m (b)
Length of swimming pool:- 20m ( l )
Therefore, the area ofor remaining part of the field ;
Area of the lawn - Area of swimming pool
= (L×B) - ( l×b)
= (60×80) - (20×6)
= 4800 - 120
= 4680 metre square .
Cost for planting grass / m square :- 30 rupees
= 4860 ×30
= 140,400 rupees .
Hope it helps !
