Find the cost of levelling the field, square in shape with one side of 20 m at the rate of ₹4.80 per m². Find the cost of fencing a rectangular field 30 m by 10 m.
Answer (1)
To solve the problem, we need to find two separate costs:
The cost of levelling a square field with one side of 20 meters.
First, calculate the area of the square field using the formula for the area of a square, which is: Area = side 2 Here, the side of the square is 20 meters: Area = 2 0 2 = 400 m 2
The cost of levelling per square meter is ₹4.80. Therefore, the total cost to level the field is: Total cost = 400 × 4.80 = ₹1920
The cost of fencing a rectangular field that measures 30 meters by 10 meters.
To find the cost of fencing, we need the perimeter of the rectangle. The formula for the perimeter P of a rectangle is: P = 2 × ( length + width ) With the length being 30 meters and the width 10 meters: P = 2 × ( 30 + 10 ) = 2 × 40 = 80 meters
Since the question does not specify the rate for fencing, we will assume the task is only to calculate the perimeter. If the cost per meter is provided or needs calculation, it should be multiplied by 80 meters.
Therefore, the cost for levelling the field is ₹1920, and the perimeter of the rectangular field for fencing is 80 meters. Details for fencing cost would depend on additional information provided about pricing.
