The kite consists of 2 triangle, EFG and EHG.
The area of EFG:

where h is the height from F to EG
The area of EHG:

where
is the height from H to EG
We also know that h + h _1 is the width of the rectangle and EG is the length of the rectangle
Thus,
Area of Kite = 
Also, Area of rectangle is rectangle length * rectangle width.
Thus, area of kite is always half of that of rectangle, the third choice is right.
Answer:
y = -
x
Step-by-step explanation:
Given that x and y vary directly then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition x = - 4, y = 6, thus
k =
=
= - 
y = -
x ← equation of variation
