The total cost of watering is ₹600.
• Given data :
Length of the lawn is 16 metres.
Breadth of the lawn is 15 metres.
Cost of watering is rupees 2.50 per square metre.
• At first we have to calculate the area of the lawn by using the following mathematical formula :
Area = Length × Breadth
= 16×15
= 240 m²
• Now,we have to calculate the total cost of watering by using the following mathematical formula :
= total area of the lawn × cost of watering per metre square
= 240×2.5
= ₹600
So,the cost of watering is ₹600. (Answer)
