The area of the fenced in rectangle with width x is f(x)= 22x - 2x². the value of x should not be 11.
<h3>What is the area of the rectangle?</h3>
The area of the rectangle is the product of the length and width of a given rectangle.
The area of the rectangle = length × Width
The perimeter of a rectangle = 2L + 2W, which given as 22 feet
where L is the length and W is the width,
2L + 2W = 22
L + W = 11
If the width of the rectangle is x feet, then the length would be (22 - 2x).
The area of the rectangle (A) is calculated as;
A = L x W
A function to find the area, in square feet, of the fenced in rectangle with width x is given by;
f(x)= x(22-2x)
f(x)= 22x - 2x²
Hence, the area of the fenced in rectangle with width x is f(x)= 22x - 2x². the value of x should not be 11.
