"The height of each triangles is 12 inches . . ."

Do you mean the height of ONE triangle is 12 inches?

The base and height of one triangle are 9 and 12 inches.

9 * 12 = 108

1/2 * 108 = 54 square inches

Now, do the same math for the other triangle and add the two together.

We'll be glad to check your answer.

Yes. The second triangle's area is 72 square inches.

Now, add 54 and 72 to find the total area of the kite.
