Here is one way to look at it....

 

This kite is made up of four right triangles:

 

 

The total area of the kite is the sum of the areas of these four triangles.

 

area of kite  =  area of red △ + area of blue △ + area of green △ + area of purple △

 

Now we need to find the area of each triangle.

 

area of a triangle  =  (1/2)(length of base)(height)

 

area of red triangle  =  (1/2)(7)(3)

 

area of blue triangle  =  (1/2)(7)(3)

 

area of green triangle  =  (1/2)(3.5)(3)

 

area of purple triangle  =  (1/2)(3.5)(3)

 

Now we can find area of kite.

 

area of kite  =  (1/2)(7)(3) + (1/2)(7)(3) + (1/2)(3.5)(3) + (1/2)(3.5)(3)

 

area of kite  =  (7)(3) + (3.5)(3)

 

area of kite  =  3(7 + 3.5)

 

area of kite  =  3(10.5)

 

area of kite  =  31.5        That is in ft2
