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 ft^{2}
