"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 sorry i did meen one triangle....
so will i take 9*16=? and then
1/2*?=? square inches 
Right.

so heres my anser
9*16=144
1/2*144=72SQUARE INCHES 
Yes. The second triangle's area is 72 square inches.
Now, add 54 and 72 to find the total area of the kite.
