Answer: Option A

Explanation:

Let's denote the length of the two shorter sides of the rectangular plot as "x" feet each, and the length of the longer sides as "3x" feet each.

The area of a rectangle is given by the formula: Area = Length x Width.

Given that the area of the plot is 432 square feet, we can write the equation:

Area = x * 3x = 3x^2.

Now, we have the equation:

3x^2 = 432.

To find the value of "x," divide both sides of the equation by 3:

x^2 = 432 / 3 x^2 = 144.

Now, take the square root of both sides to solve for "x":

x = √144 x = 12.

So, the length of the shorter sides is 12 feet, and the length of the longer sides is 3x = 3 * 12 = 36 feet.

Now, let's calculate the total length of the fence:

Two shorter sides: 2 * x = 2 * 12 = 24 feet. One longer side: 36 feet.

Total length of the fence = 24 feet + 36 feet = 60 feet.

So, the total length of the fence is 60 feet.
