    Answer:

    306mm²

    Step-by-step explanation:

    the height h = 86/2 -34 = 43-34=9mm

    the area = 34×9= 306mm²

    Answer: (I am assuming this is 2D?)

    Two bases together: 34 * 2

    68

    Two lengths together is p – two bases:

    18

    Individual length:

    9

    Area is base times length

    9 * 34

    306mm
