**The Area of a Rectangle Plot: A Comprehensive Guide**

Understanding the Problem

The area of a rectangle plot is given as 2028 m^2, and the length and breadth of the plot are in the ratio 4:3. We need to find the cost of fencing the plot at $5 per meter.

Calculating the Length and Breadth of the Plot

Let's assume the length of the plot is 4x meters and the breadth is 3x meters. Since the area of the plot is given as 2028 m^2, we can write the equation:

Area = Length x Breadth 2028 = 4x x 3x 2028 = 12x^2

Now, we need to find the value of x. To do this, we can divide both sides of the equation by 12:

x^2 = 2028 / 12 x^2 = 169 x = √169 x = 13

Now that we have the value of x, we can find the length and breadth of the plot:

Length = 4x = 4 x 13 = 52 meters Breadth = 3x = 3 x 13 = 39 meters

Calculating the Perimeter of the Plot

The perimeter of a rectangle is given by the formula:

Perimeter = 2(Length + Breadth) Perimeter = 2(52 + 39) Perimeter = 2 x 91 Perimeter = 182 meters

Calculating the Cost of Fencing the Plot

The cost of fencing the plot is given as $5 per meter. To find the total cost, we can multiply the perimeter of the plot by the cost per meter:

Total Cost = Perimeter x Cost per meter Total Cost = 182 x $5 Total Cost = $910

Conclusion

In this article, we have discussed how to find the cost of fencing a rectangle plot given its area and the ratio of its length and breadth. We have used the formula for the area of a rectangle and the perimeter of a rectangle to find the length and breadth of the plot, and then calculated the cost of fencing the plot.
