Problem 2

A farmer wants to fence his square field of length 918 meters. If the cost of fencing per meter is 5 dollars, what will be the total cost?

Okay, lets begin

The length of the field = 918 meters The cost to fence 1 meter of the field = 5 dollars. To find the total cost to fence, we find the perimeter of the field, Perimeter of the field = perimeter of the square = 4a Here a = 918 Therefore, the perimeter = 4 × 918 = 3672 meters. The cost to fence the field = 3672 × 5 = 18360 dollars. The total cost = 18360 dollars

Explanation

To find the cost to fence the field, we multiply the perimeter of the field by the cost to fence per meter.

So, the total cost is 18360 dollars.
