The window that has the shape of a kite has the area of the glass as 648 centimetre squared.
<h3>What is area of a figure?</h3>
Area can be defined as the space occupied by a flat shape or the surface of an object. Therefore,
The window is the shape of a kite. Therefore, the square meters of the glass used for the window is the area of the window(kite).
Therefore,
area of kite = ab / 2
where
- a and b are the length of the diagonal
Therefore,
a = 18 + 18 = 36 cm
b = 15 + 21 = 36 cm
area of the window = 36 × 36 / 2 = 1296 / 2 = 648 cm²

Answer:
A.
Step-by-step explanation:
In order to find the cost of the wallpaper per square foot, we must do 700.92 divided by the area of the wallpaper.
Area = length times width
Area of wallpaper = 12*9=108
700.92/108 = 700.92/108 = 6.49
The cost per a square foot is $6.49, so the answer is A.
Hope this helps :)
