Answer:  The required co-ordinates of the endpoint D are (-7, -2).

Step-by-step explanation:  Given that the midpoint of CD is E (-1,0) and one endpoint is C (5,2).

We are to find the co-ordinates of the other endpoint D.

Let (x, y) represents the co-ordinates of the endpoint D.

We know that

the co-ordinates of the midpoint of a line segment withe endpoints (a, b) and (c, d) is given by

\left(\dfrac{a+c}{2},\dfrac{b+d}{2}\right).

Therefore, according to the given information, we have

\left(\dfrac{5+x}{2},\dfrac{2+y}{2}\right)=(-1,0)\\\\\\\Rightarrow \dfrac{5+x}{2}=-1\\\\\Rightarrow 5+x=-2\\\\\Rightarrow x=-2-5\\\\\Rightarrow x=-7

and

\dfrac{2+y}{2}=0\\\\\Rightarrow 2+y=0\\\\\Rightarrow y=-2.

Thus, the required co-ordinates of the endpoint D are (-7, -2).

<h2>Answer</h2>

The answer is (2, 1)

<h2>Explanation</h2>

We can solve this by using midpoint formula

M = (x_{1} + x_2)/2, (y_1 + y_2} ) /2

because in a plane the coordinates of midpoint of a line is the average of each other coordinates.

So,

x_1 = -1, x_2 = 5

y_1 = 0. y_2 = 2

Putting values in formula as

M = (-1+5) / 2, (0+2) / 2

M = (2, 1)

11*2 = 22 (calculating the diameter)

Using πD for the area:
π * 22 = 22π

Getting 3/4 of the area because the dog can not move past the corners of the garage;

22π * 3/4 = 16.5π

Getting the answer in feet^2:
16.5 * 3.14 = 51.84 feet^2

Hope this helps! :)
