Kite WXYZ is graphed on a coordinate plane.

What is the approximate perimeter of the kite? Round to the nearest tenth.

10.6 units
11.5 units
14.0 units
16.2 units

Answer :

Answer:

Perimeter of the kite is 16.2 units rounding of to the nearest tenth.

Step-by-step explanation:

Since, WXYZ is a kite, two separate pairs of repeated sides are congruent

This means,

WX=XY

WZ=ZY

∴, perimeter of kite WXYZ is = 2 (WX + WZ) Bar

(WX)Bar = [tex]\sqrt{(1-3){{2} \atop}\++(1+4){{2} \atop} } = \sqrt{(-2){{2} \atop}\++(-3){{2} \atop}} = \sqrt{(4+9)} = \sqrt{13}[/tex]

(WZ)Bar = [tex]\sqrt{(1-3){{2} \atop}\++(1+3){{2} \atop} } = \sqrt{(-2){{2} \atop}\++(+4){{2} \atop}} = \sqrt{(4+16)} = \sqrt{20}[/tex]

Hence, Perimeter P = [tex]2(\sqrt{13} + \sqrt{20} ) = 16.15[/tex] ≈ 16.2 Units

Answer:

16.2
