The cost of fencing a square field at 40 paise per meter is rs 2000.find the cost of watering the field at 80 paise per 100msquare

Your right I think

To find the cost of watering the field, we first need to calculate the area of the field.

Given that the field is a square and the cost of fencing is Rs 2000, we can use that information to find the side length of the square field.

The formula for the perimeter of a square is P = 4s, where P is the perimeter and s is the length of each side.

Since we know the cost of fencing (Rs 2000), we can use the formula to calculate the perimeter:

2000 = 4s

To find the value of s (side length), we divide both sides of the equation by 4:

s = 2000/4
s = 500 meters

Now that we know the side length of the square field is 500 meters, we can calculate the area of the field.

The formula for the area of a square is A = s^2, where A is the area and s is the length of each side.

A = 500 * 500
A = 250000 square meters

Now that we have the area of the field (250000 square meters), we can calculate the cost of watering.

Given that the cost of watering is 80 paise per 100 square meters, we can set up the equation:

Cost of watering = (Area / 100) * Cost per 100 square meters
Cost of watering = (250000 / 100) * 80 paise
Cost of watering = 2500 * 80 paise
Cost of watering = Rs 2000

Therefore, the cost of watering the field at 80 paise per 100 square meters is Rs 2000.

If the side of the field has length x, then

4x = 2000/40 = 50
x = 25/2

80 * (25/2)^2 / 100 = 125
