Answer:
The correct option is d.
Step-by-step explanation:
Area of a triangle is
[tex]A=\frac{1}{2}\times base\times height[/tex]
The given kite has two congruent triangles with base 9 and height 4.
The area of kite is twice of the area of triangle with base 9 and height 4.
[tex]\text{Area of kite}=2\times \text{Area of a triangle with base 9 and height 4}[/tex]
[tex]\text{Area of kite}=2\times (\frac{1}{2}\times 9\times 4)[/tex]
[tex]\text{Area of kite}=36[/tex]
The area of kite is 36 square units.
Therefore the correct option is d.
