<u>Answer-</u>

<em>Perimeter of the kite is </em><em>16.2 units</em>

<u>Solution-</u>

As WXYZ is a kite, so two disjoint pairs of consecutive sides are congruent, i.e WX=XY and WZ=ZY

So, perimeter of the kite WXYZ is,

=2(\overline{WX}+\overline{WZ})

And

\overline{WX}=\sqrt{(1-3)^2+(1-4)^2}=\sqrt{(-2)^2+(-3)^2}=\sqrt{4+9}=\sqrt{13}

\overline{WZ}=\sqrt{(1-3)^2+(1+3)^2}=\sqrt{(-2)^2+(4)^2}=\sqrt{4+16}=\sqrt{20}

So, perimeter will be,

P=2(\sqrt{13}+\sqrt{20})=16.15\approx 16.2\ units

Answer:

D. 16.2 units.

Step-by-step explanation:

We have been given an image of a kite on coordinate plane and we are asked to find the perimeter of our given kite.

Since we know that a kite has two disjoint pairs of congruent consecutive sides, so the perimeter of our given kite will be 2 times the sum of side XY and YZ.

To find the length of sides XY and YZ we will use distance formula.

\text{Distance}=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Upon substituting coordinates of point X and Y in above formula we will get,

\text{Distance between point X and Y}=\sqrt{(3-5)^2+(4-1)^2}

\text{Distance between point X and Y}=\sqrt{(-2)^2+(3)^2}

\text{Distance between point X and Y}=\sqrt{4+9}

\text{Distance between point X and Y}=\sqrt{13}

Now similarly we will find the length of segment YZ.

\text{Distance between point Y and Z}=\sqrt{(5-3)^2+(1--3)^2}

\text{Distance between point Y and Z}=\sqrt{(2)^2+(1+3)^2}

\text{Distance between point Y and Z}=\sqrt{4+(4)^2}

\text{Distance between point Y and Z}=\sqrt{4+16}

\text{Distance between point Y and Z}=\sqrt{20}

\text{Distance between point Y and Z}=2\sqrt{5}

\text{Perimeter of kite WXYZ}=2(XY+YZ)

\text{Perimeter of kite WXYZ}=2(\sqrt{13}+2\sqrt{5})

\text{Perimeter of kite WXYZ}=2(3.6055512754639893+4.4721359549995794)

\text{Perimeter of kite WXYZ}=2(8.0776872304635687)

\text{Perimeter of kite WXYZ}=16.1553744609271374\approx 16.2

Therefore, the perimeter of the kite WXYZ is 16.2 units and option D is the correct choice.
