Calculate the total expense to fence a circular field with a diameter of 28 meters if the fencing costs Rs. 1.50 per meter.

Explanation

The circumference of the circular field is calculated using the formula C = π × diameter = 3.14 × 28 = 87.92 meters. Multiplying the circumference by the cost per meter: 87.92 × 1.50 = Rs. 131.88, which rounds to Rs. 132. Therefore, the cost of fencing is Rs. 132.
