Answer:
₹140400.00
Step-by-step explanation:
Area of lawn = 80m × 60m = 4800m²
Area of the swimming pool = 20m × 6m = 120m²
Remaining part = Area of lawn - Area of pool
= 4800m² - 120m² = 4680m²
Now,
Cost of putting grass per metre square = ₹30
Therefore, cost of putting grass on 4680m² = ₹(30 × 4680)
= ₹140400
For better understanding, I have attached a diagram,
Hope it helps....

QUESTIONS :-
Q. a lawn is 80 metre long and 60 metre wide. there is a swimming pool of length 20 metre x 6 metre in the lawn. what will be the cost of putting grasses in the remaining part of the field at rupees 30 per square metre?
GIVEN :-
- A Lawn is 80m long 60m wide
- the length of swimming pool is 20m and width is 6m
- charge for putting grass around the swimming that cost ₹30/m²
AIM OF THE QUESTION :-
- to find the cost that required to cover the grass in remaining space of field
WHAT WE NEED TO FIND ?
→ area of lawn
→ area of swimming pool
→ charge required to cover the field with grass
⇒AREA OF LAWN
- length = 80m
- width = 60cm
area of lawn = area of rectangle
= length × width
= 80 m × 60m
= 4800m² --------------(I)
⇒AREA OF SWIMMING POOL
- length= 20cm
- width = 6m
area of swimming pool = area of rectangle
= length × width
= 20 m × 6m
= 120m² ----------(II)
๏ now to find the remaining part of lawn
= area of lawn - area of swimming pool
= equation (I) - equation (II)
= 4800m² - 120m²
= 4680 m²
⇒Cost of putting grasses in the remaining part of the field .
- we know that the cost of putting grass in the remaining part of the field is ₹30/m²
1 m² = ₹30
so , 4860m² =
4860 m² × ₹30
= ₹140400
therefore , the price of putting grass in remaining part of field is ₹140400 .
