    "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.
