The cost of fencing a square field at rupees 1.60per meter is rupees 3200. Find the cost of reaping the field at rupees1.20per 100sq . meter

number of metres of fencing = 3200/1.6 = 2000 m

so each side of the square is 2000/4 or 500 m
and its area is 500^2 m^2

cost of "reaping" = 500^2 /100 * 1.2
= 3000 rupees

To find the cost of reaping the field, we need to determine the area of the square field first.

Given:
- Cost of fencing a square field = Rs 3200
- Cost of fencing per meter = Rs 1.60

Let's calculate the perimeter of the square field using the cost of fencing and the cost per meter:

Perimeter of the field = Total cost / Cost per meter
Perimeter of the field = Rs 3200 / Rs 1.60 = 2000 meters

Since the field is a square, the perimeter is equal to 4 times the length of one side. So, we can find the length of one side by dividing the perimeter by 4:

Length of one side = Perimeter / 4
Length of one side = 2000 meters / 4 = 500 meters

Now that we know the length of one side, we can calculate the area of the square field by squaring the length:

Area of the field = (Length of one side)^2
Area of the field = 500 meters * 500 meters = 250000 square meters

Given:
- Cost of reaping per 100 square meters = Rs 1.20

To find the cost of reaping the field, we need to determine how many 100 square meter areas are there in the total area of the field.

Number of 100 square meter areas = Area of the field / 100
Number of 100 square meter areas = 250000 square meters / 100 = 2500

Finally, we can find the cost of reaping the field by multiplying the number of 100 square meter areas by the cost per 100 square meters:

Cost of reaping the field = Number of 100 square meter areas * Cost per 100 square meters
Cost of reaping the field = 2500 * Rs 1.20 = Rs 3000

Therefore, the cost of reaping the field at Rs 1.20 per 100 square meters is Rs 3000.

((3200/1.60)/4)^2 * 1.20/100 = 3000
