The length and width of the given rectangle are 52 ft and 48 ft respectively.
<h3><u>Solution:</u></h3>
The relationship between the length and breadth is given as following:
The length is 4 more feet than the width
The perimeter of the rectangle is given as 200 ft.
The formula to find the perimeter of a rectangle is:
Perimeter = 2(length + width)
Let length and width of the rectangle be denoted as ‘L’ and ‘B’
The given relationship between length and width can be written in equation form as follows:
L = 4 + B ------ eqn 1
Substitute the value of "L" in perimeter of triangle
200 = 2(4 + B + B)
200 = 2(4 + 2B)
200 = 8 + 4B
4B = 192
B = 48
Since, we know the value of width lets substitute it in eq1 to find the length.
L = 4 + 48
L = 52
Therefore, the length and width of the given rectangle are 52 ft and 48 ft respectively.

Answer:
D is correct. 
Step-by-step explanation:
We are given the root of the equation

If we are given solution of the equation then find equation using formula.
If a and b are the solution of equation then equation would be (x-a)(x-b)=0
Here, 
Equation form would be 
Now we simplify the above equation to get correct option.


So, D is correct. 
The slope is -10, I used a graph for this.
The area is about 62.4 inch square
