    Answer:

    The height is 8 cm

    Step-by-step explanation:

    The area of a triangle is

    A = 1/2 bh

    72 = 1/2 (18)h

    72 = 9h

    Divide each side by 9

    72/9 = 9h/9

    8 = h

    The height is 8 cm

    Answer:

    8cm

    Step-by-step explanation:

    let y represent height

    Area of a triangle=½base×height=72cm²

    72cm²=½×18cm×y

    72cm²=9cmy

    72cm²/9cm=9cmy/9cm

    8cm=y
