    You can think of the kite as being made up of the 4 small triangles shown above.

    The kite is made up of the triangles called 1a, 2a, 3a, and 4a.

    Triangles 1a and 1b have the same area. Triangles 2a and 2b have the same area. Triangles 3a and 3b have the same area. Triangles 4a and 4b have the same area.

    That means the area of the kite is half the area of the outer large rectangle.

    The area of a kite is the product of the diagonals divided by 2. Example: |dw:1436148929227:dw|

    110.5?

    The diagonals of your kite are 6 in. + 13 in. and 8.5 in. + 8.5 in. Do those additions. Then multiply the sums together and divide by 2.

    How did you get 110.5?

    I multiplied 10x11 and got 220 then divided it by 2 and got 110.5

    First, 10 * 11 = 110, not 220. Where did you get 10 and 11 from? I don't see those numbers in the figure.
