Final answer:
To find the total area of an enclosed area with a given number of feet of fencing, you can use the concept of turning the shape into a square or a rectangle and calculate the area using the length and width of the shape.
Step-by-step explanation:
To find the total area of an enclosed area with a given number of feet of fencing, you can use the concept of turning the shape into a square or a rectangle. Let's take an example where the shape is a rectangle. The perimeter of the rectangle will be the sum of all four sides. If you know the length and width of the rectangle, you can calculate the area by multiplying the length and width together.
For example, if the perimeter is 40 feet and the length is 10 feet, then the width will be (40 - 2x10) / 2 = 10 feet. The area of the rectangle will be 10 feet x 10 feet = 100 square feet.
