The cost of putting grass in the remaining part of the field = Rs 1,40,400
- Area of a rectangle = length * breadth
- Area of the lawn = 80 m * 60 m
= 4800 square meter
- Area of the swimming pool = 20 m * 6 m
= 120 square meter
- Remaining area of lawn = (4800 - 120) square meter
= 4680 square meter
- Cost of putting grass in the remaining part of the field = 4680 * 30
= Rs 1,40,400
